Expand description
A WebAssembly translation error.
When a WebAssembly function can’t be translated, one of these error codes will be returned to describe the failure.
Variants§
InvalidWebAssembly
The input WebAssembly code is invalid.
This error code is used by a WebAssembly translator when it encounters invalid WebAssembly code. This should never happen for validated WebAssembly code.
Fields
Unsupported(String)
A feature used by the WebAssembly code is not supported by the embedding environment.
Embedding environments may have their own limitations and feature restrictions.
ImplLimitExceeded
An implementation limit was exceeded.
Cranelift can compile very large and complicated functions, but the implementation has limits that cause compilation to fail when they are exceeded.
User(String)
Any user-defined error.
