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`

Fields

message: String

A string describing the validation error.

offset: usize

The bytecode offset where the error occurred.

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.

`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.

`Middleware(MiddlewareError)`

An error from the middleware error.

`Generic(String)`

A generic error.
