<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>
<li>update criterion requirement from 0.4 to 0.5 (<a

<li>Remove unused libz-sys (<a
href="https://redirect.github.com/tokio-rs/prost/issues/1077">#1077</a>)</li>
<li>build(deps): update itertools requirement from >=0.10, <!-- raw
HTML omitted -->=0.10, <=0.13 (<a
href="https://redirect.github.com/tokio-rs/prost/issues/1070">#1070</a>)</li>
</ul>
<h2>Documentation</h2>
<ul>
<li>better checking of tag duplicates, avoid discarding invalid variant
errs (<a

</ul>
<h2>Internal</h2>
<ul>
<li>workspace package metadata (<a

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.
