Required Methods§
sourcefn filesystem_error_code(
&mut self,
err: Resource<Error>,
) -> Result<Option<ErrorCode>>
fn filesystem_error_code( &mut self, err: Resource<Error>, ) -> Result<Option<ErrorCode>>
Attempts to extract a filesystem-related error-code
from the stream
error
provided.
Stream operations which return stream-error::last-operation-failed
have a payload with more information about the operation that failed.
This payload can be passed through to this function to see if there’s
filesystem-related information about the error to return.
Note that this function is fallible because not all stream-related errors are filesystem-related errors.
