Enum wasmer_compiler::WasmError

pub enum WasmError {
    InvalidWebAssembly {
        message: String,
        offset: usize,
    },
    Unsupported(String),
    ImplLimitExceeded,
    Middleware(MiddlewareError),
    Generic(String),
}

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 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.

Middleware(MiddlewareError)

An error from the middleware error.

Generic(String)

A generic error.

Trait Implementations

impl Debug for WasmError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for WasmError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for WasmError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
