* Shrink the size of the anyfunc table in `VMContext` This commit shrinks the size of the `VMCallerCheckedAnyfunc` table allocated into a `VMContext` to be the size of the number of "escaped" functions in a module rather than the number of functions in a module. Escaped functions include exports, table elements, etc, and are typically an order of magnitude smaller than the number of functions in general. This should greatly shrink the `VMContext` for some modules which while we aren't necessarily having any problems with that today shouldn't cause any problems in the future. The original motivation for this was that this came up during the recent lazy-table-initialization work and while it no longer has a direct performance benefit since tables aren't initialized at all on instantiation it should still improve long-running instances theoretically with smaller `VMContext` allocations as well as better locality between anyfuncs. * Fix some tests * Remove redundant hash set * Use a helper for pushing function type information * Use a more descriptive `is_escaping` method * Clarify a comment * Fix condition
Wasmtime Embedding API
The wasmtime crate is an embedding API of the wasmtime WebAssembly runtime.
This is intended to be used in Rust projects and provides a high-level API of
working with WebAssembly modules.
If you're interested in embedding wasmtime in other languages, you may wish to
take a look a the C embedding API instead!
