Required Methods

fn http_error_code( &mut self, err: Resource<Error>, ) -> Result<Option<ErrorCode>, Error>

Attempts to extract a http-related error from the wasi:io error provided.

Stream operations which return wasi:io/stream/stream-error::last-operation-failed have a payload of type wasi:io/error/error with more information about the operation that failed. This payload can be passed through to this function to see if there’s http-related information about the error to return.

Note that this function is fallible because not all io-errors are http-related errors.

fn convert_error_code(&mut self, err: HttpError) -> Result<ErrorCode, Error>
