b8e97b5b - Define a `TryClone` trait for cloning with fallible allocation (#12519)

Wed, 04 Feb 2026 18:24:32 +0000

Define a `TryClone` trait for cloning with fallible allocation (#12519)* Define a `TryClone` trait for cloning with fallible allocationPart of https://github.com/bytecodealliance/wasmtime/issues/12069* add reason to `allow` annotation List of files: /wasmtime-44.0.1/crates/core/src/alloc.rs

28f6f5e7 - Add fallible `try_collect` to collections (#12505)

Tue, 03 Feb 2026 19:27:54 +0000

Add fallible `try_collect` to collections (#12505)* Add fallible `try_collect` to collectionsThis adds a new `TryCollect` extension trait to `wasmtime-core` whichenables `iter.try_collect()` to fallibly collect into a `Vec` or`Box<[T]>` while handling OOM. This is intended to serve as areplacement for the `new_boxed_slice_*` helpers in appropriatesituations since it more closely matches what Wasmtime likely alreadydoes today where we throw `.collect()` on iterators.* Extend oom tests a bit more* Use a TryExtend trait* Fix oom tests List of files: /wasmtime-44.0.1/crates/core/src/alloc.rs
