Trait TxMetadata 

pub trait TxMetadata:
    Default
    + Debug
    + Send
    + Sync
    + 'static {
    // Required methods
    fn socket_info(&self) -> Option<SocketInfo>;
    fn checksum_offload_result(&self) -> Option<ChecksumOffloadResult>;
    fn set_checksum_offload_result(
        &mut self,
        result: Option<ChecksumOffloadResult>,
    );
}

A trait for the metadata associated with a TX frame.

The Default impl yields the default, i.e. unspecified, metadata instance.

Required Methods

fn socket_info(&self) -> Option<SocketInfo>

Returns SocketInfo for the socket associated with the packet. None is returned if the packet is not associated with a local socket.

fn checksum_offload_result(&self) -> Option<ChecksumOffloadResult>

Returns the result of TX checksum offloading, if any was performed.

fn set_checksum_offload_result(&mut self, result: Option<ChecksumOffloadResult>)

Sets the TX checksum offload result. Replaces the previous result if called multiple times.

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.
