Required Methods§
Sourcefn http_error_code(
&mut self,
err: Resource<IoError>,
) -> Result<Option<ErrorCode>>
fn http_error_code( &mut self, err: Resource<IoError>, ) -> Result<Option<ErrorCode>>
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>
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
