Enum Error

pub enum Error<E = Infallible> {
    CanonicalizedHeapTypeReference,
    InvalidConstExpr,
    InvalidCodeSectionSize,
    UnexpectedNonCoreModuleSection,
    UnexpectedNonComponentSection,
    UnsupportedCoreTypeInComponent,
    ParseError(BinaryReaderError),

}

Available on crate feature wasmparser only.

An error when re-encoding from wasmparser to wasm-encoder.

Variants

CanonicalizedHeapTypeReference

There was a type reference that was canonicalized and no longer references an index into a module’s types space, so we cannot encode it into a Wasm binary again.

InvalidConstExpr

The const expression is invalid: not actually constant or something like that.

InvalidCodeSectionSize

The code section size listed was not valid for the wasm binary provided.

UnexpectedNonCoreModuleSection

There was a section that does not belong into a core wasm module.

UnexpectedNonComponentSection

There was a section that does not belong into a compoennt module.

UnsupportedCoreTypeInComponent

A core type definition was found in a component that’s not supported.

ParseError(BinaryReaderError)

There was an error when parsing.

UserError(E)

There was a user-defined error when re-encoding.

Trait Implementations

impl<E: Debug> Debug for Error<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for Error<E>

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

Formats the value using the given formatter.

impl<E: 'static + Error> Error for Error<E>

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl<E> From<BinaryReaderError> for Error<E>

fn from(err: BinaryReaderError) -> Self

Converts to this type from the input type.
