Forbid rustdoc warnings in CI (#12420)* Forbid rustdoc warnings in CIThis commit corrects our handling of rustdoc flags in CI to ensure thatwarnings indeed fire. Additionally this changes our flags to pass`-Dwarnings` to ensure that we have warning-free doc builds when allfeatures are enabled at least.There were quite a lot of preexisting issues to fix, so thisadditionally goes through and fixes all the warnings that cropped up.* Update nightly toolchain againprtest:full* Update another nightly* Fix a warning in generated code List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/exception.rs

96e19700 - Migrate the `wasmtime` crate to `wasmtime_environ::error::*` (#12231)

Wed, 07 Jan 2026 17:08:11 +0000

Migrate the `wasmtime` crate to `wasmtime_environ::error::*` (#12231)* Migrate the `wasmtime` crate to `wasmtime_environ::error::*`Instead of `anyhow::Error`.This commit re-exports the `wasmtime_environ::error` as the `wasmtime::error`module, updates the prelude to include these new error-handling types, redirectsour top-level `wasmtime::{Error, Result}` re-exports to re-export`wasmtime::error::{Error, Result}`, and updates various use sites that weredirectly using `anyhow` to use the new `wasmtime` versions.This process also required updating the component macro and wit-bindgen macro touse the new error types instead of `anyhow`.Part of https://github.com/bytecodealliance/wasmtime/issues/12069* Replace wasmtime::error::Thing with wasmtime::Thing where it makes sense* cargo fmt* Move `crate::error::Thing` to `crate::Thing` where it makes sense List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/exception.rs

2d25f862 - WebAssembly exception-handling support. (#11326)

Thu, 21 Aug 2025 02:55:44 +0000

WebAssembly exception-handling support. (#11326)* WebAssembly exception-handling support.This PR introduces support for the [Wasm exception-handling proposal],which introduces a conventional try/catch mechanism to WebAssembly. ThePR supports modules that use `try_table` to register handlers for alexical scope; and provides `throw` and `throw_ref` that allocate (inthe first case) and throw exception objects.This PR builds on top of the work in #10510 for Cranelift-levelexception support, #10919 for an unwinder, and #11230 for exceptionobjects built on top of GC, in addition a bunch of smaller fix andenabling PRs around those.[Wasm exception-handling proposal]: https://github.com/WebAssembly/exception-handling/prtest:full* Permit UnwindToWasm to have unused fields in Pulley builds (for now).* Resolve miri-caught reborrowing issue.* Ignore exceptions tests in miri for now (Pulley not supported).* Use wasmtime_test on exceptions tests.* Get tests passing on pulley platforms* Add a check to `supports_host` for the generated test and assert failure also when that is false.* Remove `pulley_unsupported` test as it falls out of `#[wasmtime_test]`* Remove `exceptions_store` helper as it falls out of `#[wasmtime_test]`* Remove miri annotations as they fall out of `#[wasmtime_test]`* Remove dead import* Skip some unsupported tests entirely in `#[wasmtime_test]`If the selected compiler doesn't support the host at all then there's noneed to run it. Actually running it could misinterpret `CraneliftNative`as "run with pulley" otherwise, so avoid such false negatives.* Cranelift: dynamic contexts: account for outgoing-args area.---------Co-authored-by: Alex Crichton List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/exception.rs
