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.

Show fields

Fields of InvalidWebAssembly

message: String

A string describing the validation error.

offset: usize

The bytecode offset where the error occurred.

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.
