Struct Error 

pub struct Error { /* private fields */ }

A binary reader for WebAssembly modules.

Implementations

impl Error

pub fn message(&self) -> &str

Get this error’s message.

pub fn offset(&self) -> usize

Get the offset within the Wasm binary where the error occurred.

pub fn missing_wasm_feature(&self) -> Option<WasmFeatures>

Returns Some if this error is due to a disabled Wasm feature.

If the features crate feature is enabled, a returned WasmFeatures will contain a feature that could be enabled to prevent this error.

Note: This is not comprehensive; None may be returned in some cases where enabling a feature could avoid the error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for WasmError

fn from(e: Error) -> WasmError

Convert from a BinaryReaderError to a WasmError.

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

fn from(err: Error) -> Error<E>

Converts to this type from the input type.
