* Add Wasmtime-specific C API functions to return errors This commit adds new `wasmtime_*` symbols to the C API, many of which mirror the existing counterparts in the `wasm.h` header. These APIs are enhanced in a number of respects: * Detailed error information is now available through a `wasmtime_error_t`. Currently this only exposes one function which is to extract a string version of the error. * There is a distinction now between traps and errors during instantiation and function calling. Traps only happen if wasm traps, and errors can happen for things like runtime type errors when interacting with the API. * APIs have improved safety with respect to embedders where the lengths of arrays are now taken as explicit parameters rather than assumed from other parameters. * Handle trap updates * Update C examples * Fix memory.c compile on MSVC * Update test assertions * Refactor C slightly * Bare-bones .NET update * Remove bogus nul handling
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!
