Both [as_ptr][as_ptr] and [as_mut_ptr][as_mut_ptr] are allowed to return
a dangling raw pointer when the Vec size is 0.
The idea is that you should guard that read checking the size. This
probably works well in most cases, but at the very least in the
java-sdk, the JNA machinery tries to be helpful and it dereferences the
pointer, causing a SIGSEGV.
The solution is to check if the resulting vector is empty and return
null instead. A new, empty vector would be better, but I think that
would not solve the problem, because the problem is caused by a new,
empty vector in the first place.
Caveat: this might break consumers downstream.
On the other hand: consumers that do not check for the nInput, nOutput
counts are just waiting to explode, like JNA.

<blockquote>
<h1>Prost version 0.13.1</h1>
<p><em>PROST!</em> is a <a
href="https://developers.google.com/protocol-buffers/">Protocol
Buffers</a> implementation for the <a
href="https://www.rust-lang.org/">Rust Language</a>. <code>prost</code>
generates simple, idiomatic Rust code from <code>proto2</code> and
<code>proto3</code> files.</p>
<h2>Bug fixes</h2>
<ul>
<li>Enum variant named Error causes ambiguous item (<a
href="https://redirect.github.com/tokio-rs/prost/issues/1098">#1098</a>)</li>
</ul>
<h1>PROST version 0.13.0</h1>
<p><strong>note</strong>: this version was yanked in favor of 0.13.1</p>
<p><em>PROST!</em> is a <a
href="https://developers.google.com/protocol-buffers/">Protocol
Buffers</a> implementation for the <a
href="https://www.rust-lang.org/">Rust Language</a>. <code>prost</code>
generates simple, idiomatic Rust code from <code>proto2</code> and
<code>proto3</code> files.</p>
<p>This major update brings new features and fixes:</p>
<h2>Breaking changes</h2>
<ul>
<li>
<p>derive Copy trait for messages where possible (<a
href="https://redirect.github.com/tokio-rs/prost/issues/950">#950</a>)</p>
<p><code>prost-build</code> will automatically derive <code>trait
Copy</code> for some messages. If you manually implement
<code>Copy</code> you should remove your implementation.</p>
</li>
<li>
<p>Change generated functions signatures to remove type parameters (<a
href="https://redirect.github.com/tokio-rs/prost/issues/1045">#1045</a>)</p>
<p>The function signature of <code>trait Message</code> is changed to
use <code>impl Buf</code> instead of a named generic type. If you
implement <code>trait Message</code>, you should change the function
signature.</p>
</li>
<li>
<p>Lightweight error value in TryFrom<!-- raw HTML omitted --> for enums
(<a
href="https://redirect.github.com/tokio-rs/prost/issues/1010">#1010</a>)</p>
<p>When a <code>impl TryFrom<i32></code> is generated by
<code>prost</code> derive macros, it will now return the error type
<code>UnknownEnumValue</code> instead of <code>DecodeError</code>. The
new error can be used to retreive the integer value that failed to
convert.</p>
</li>
</ul>
<h2>Features</h2>
<ul>
<li>
<p>fix: Only touch include file if contents is changed (<a
href="https://redirect.github.com/tokio-rs/prost/issues/1058">#1058</a>)</p>
<p>Most generated files are untouched when the contents doesn't change.
Use the same mechanism for include file as well.</p>
</li>
</ul>
<h2>Dependencies</h2>
<ul>
<li>update env_logger requirement from 0.10 to 0.11 (<a
href="https://redirect.github.com/tokio-rs/prost/issues/1074">#1074</a>)</li>

HTML omitted -->=0.10, <=0.13 (<a
href="https://redirect.github.com/tokio-rs/prost/issues/1070">#1070</a>)</li>
</ul>
<h2>Documentation</h2>

This is a rough POC for allowing people to whitelist a dir as readonly.
When the source path is prefixed with `ro:`, the dir is considered as
readonly. This preserved backward compatibility. This suggestion came up
in https://github.com/extism/go-sdk/pull/1#discussion_r1276700587
Readonly:
```rs
let manifest = Manifest::new([url])
.with_allowed_path("ro:D:/x/rust/fs/data".to_string(), "/data")
.with_config_key("path", "/data/data.txt");
```
```

- Breaking: No longer copies Extism config values into WASI environment
variables because the new interface doesn't allow for the environment to
be updated - these should be accessed using the Extism config functions
instead
- Requires wasmtime 20 or greater
- Enables wasm-gc
- Similar to https://github.com/extism/extism/pull/697 without sockets
or additional support for command modules
https://github.com/extism/dotnet-pdk/pull/84 brought to my attention
that the Rust SDK supports both `headers` and `header` while the go sdk
only supports `headers`. After talking to Zach, we decided to remove the
`header` alias from the Rust SDK too, since it's obsolete and we want
people to use `headers`
Currently HTTP requests can extend beyond the configured timeout for a
plugin - this PR sets the timeout of the HTTP request to the remaining
time left if a timeout is set in the manifest.
Add `plugin.call_with_host_context` and `current_plugin.host_context`
methods, enabling per-call context to be looped from the guest invocation
to any host functions it calls. In an HTTP server environment, this enables
re-using a plugin across multiple requests while switching out backing
connections and user information in host functions. (Imagine a host
function, `update_user` -- previously the plugin would have to have been
aware of the user to pass to the host function. Now that information is
ambient.)
This is a backwards-compatible change and requires no changes to
existing plugins.
Implement by adding a global, mutable externref to the extism kernel.
Since most programming languages, including Rust, don't let you define
these natively, we accomplish this by using `wasm-merge` to combine the
kernel Wasm with Wasm generated by a WAT file containing only the
global.
(This pattern might be useful for other Wasm constructs we can't use
directly from Rust, like `v128` in argument parameters.)
Wasmtime requires extern refs to be `Any + Send + Sync + 'static`; we
additionally add `Clone`. I haven't tried this with an `Arc` directly,
but it should work at least for container structs that hold `Arc`'s
themselves.
Some of the old constants conflicted with Perl headers used for build
Perl extensions such the
[perl-sdk](002e4437ac/Extism/lib/Extism/XS.xs).
This fix would allow removing the copy of extism.h (inlined in that file
linked) out of the perl-sdk.
These constants especially `I32` likely have conflicts with many other
large C codebases.
A new extism release with this fix should not be made until the affected
sdks (cpp-sdk) have an update ready.
- Adds `memory.max_var_bytes` to the manifest to limit the number of
bytes allowed to be stored in Extism vars - if `max_var_bytes` is set to
0 then vars are disabled.
- Adds some builder functions to `MemoryOptions` struct
- Sets the default var store size to 1mb
- Includes a test to make sure `var_set` returns an error when the limit
is reached
Updates the requirements on
[base64](https://github.com/marshallpierce/rust-base64) to permit the
latest version.

<p><em>Sourced from <a
href="https://github.com/marshallpierce/rust-base64/blob/master/RELEASE-NOTES.md">base64's
changelog</a>.</em></p>
<blockquote>
<h1>0.22.0</h1>
<ul>
<li><code>DecodeSliceError::OutputSliceTooSmall</code> is now
conservative rather than precise. That is, the error will only occur if
the decoded output <em>cannot</em> fit, meaning that
<code>Engine::decode_slice</code> can now be used with exactly-sized
output slices. As part of this, <code>Engine::internal_decode</code> now
returns <code>DecodeSliceError</code> instead of
<code>DecodeError</code>, but that is not expected to affect any
external callers.</li>
<li><code>DecodeError::InvalidLength</code> now refers specifically to
the <em>number of valid symbols</em> being invalid (i.e. <code>len % 4
== 1</code>), rather than just the number of input bytes. This avoids
confusing scenarios when based on interpretation you could make a case
for either <code>InvalidLength</code> or <code>InvalidByte</code> being
appropriate.</li>
<li>Decoding is somewhat faster (5-10%)</li>
</ul>
<h1>0.21.7</h1>
<ul>
<li>Support getting an alphabet's contents as a str via
<code>Alphabet::as_str()</code></li>
</ul>
<h1>0.21.6</h1>
<ul>
<li>Improved introductory documentation and example</li>
</ul>
<h1>0.21.5</h1>
<ul>
<li>Add <code>Debug</code> and <code>Clone</code> impls for the general
purpose Engine</li>
</ul>
<h1>0.21.4</h1>
<ul>
<li>Make <code>encoded_len</code> <code>const</code>, allowing the
creation of arrays sized to encode compile-time-known data lengths</li>
</ul>
<h1>0.21.3</h1>
<ul>
<li>Implement <code>source</code> instead of <code>cause</code> on Error
types</li>
<li>Roll back MSRV to 1.48.0 so Debian can continue to live in a time
warp</li>
<li>Slightly faster chunked encoding for short inputs</li>
<li>Decrease binary size</li>
</ul>
<h1>0.21.2</h1>
<ul>
<li>Rollback MSRV to 1.57.0 -- only dev dependencies need 1.60, not the
main code</li>
</ul>
<h1>0.21.1</h1>
<ul>
<li>Remove the possibility of panicking during decoded length
calculations</li>
<li><code>DecoderReader</code> no longer sometimes erroneously ignores
padding <a

It looks like when a module is added to the linker, all of its imports
must already be present. This PR updates the linking process to take
that into consideration and adds a test with a reproduction of the issue
@chrisdickinson shared with me.
