Required Methods§

Source

fn async_map_err<F, R>(self, f: F) -> Result<T, R>
where F: FnMut(E) -> R,

Map the error type contained in the result (if present) preserving Ok and Err(Error::WouldBlock)

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
