* Document and update the API of the `externals.rs` module This commit ensures that all public methods and items are documented in the `externals.rs` module, notably all external values that can be imported and exported in WebAssembly. Along the way this also tidies up the API and fixes a few bugs: * `Global::new` now returns a `Result` and fails if the provided value does not match the type of the global. * `Global::set` now returns a `Result` and fails if the global is either immutable or the provided value doesn't match the type of the global. * `Table::new` now fails if the provided initializer does not match the element type. * `Table::get` now returns `Option<Val>` instead of implicitly returning null. * `Table::set` now returns `Result<()>`, returning an error on out of bounds or if the input type is of the wrong type. * `Table::grow` now returns `Result<u32>`, returning the previous number of table elements if succesful or an error if the maximum is reached or the initializer value is of the wrong type. Additionally a bug was fixed here where if the wrong initializer was provided the table would be grown still, but initialization would fail. * `Memory::data` was renamed to `Memory::data_unchecked_mut`. Additionally `Memory::data_unchecked` was added. Lots of caveats were written down about how using the method can go wrong. * `Memory::grow` now returns `Result<u32>`, returning an error if growth fails or the number of pages previous the growth if successful. * Run rustfmt * Fix another test * Update crates/api/src/externals.rs Co-Authored-By: Sergei Pepyakin <s.pepyakin@gmail.com> Co-authored-by: Sergei Pepyakin <s.pepyakin@gmail.com>
This is the wasmtime-wast crate, which contains an implementation of WebAssembly's
"wast" test scripting language, which is used in the
WebAssembly spec testsuite, using wasmtime for execution.
