Trait Host 

pub trait Host: HostNetwork + Send {
    // Required method
    fn network_error_code(
        &mut self,
        err: Resource<Error>,
    ) -> impl Future<Output = Result<Option<ErrorCode>>> + Send;
}

Required Methods

fn network_error_code( &mut self, err: Resource<Error>, ) -> impl Future<Output = Result<Option<ErrorCode>>> + Send

Attempts to extract a network-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 network-related information about the error to return.

Note that this function is fallible because not all stream-related errors are network-related errors.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
