Trait TxToken

pub trait TxToken {
    // Required method
    fn consume<R, F>(self, len: usize, f: F) -> R
       where F: FnOnce(&mut [u8]) -> R;
}

A token to transmit a single network packet.

Required Methods

fn consume<R, F>(self, len: usize, f: F) -> R

where F: FnOnce(&mut [u8]) -> R,

Consumes the token to send a single network packet.

This method constructs a transmit buffer of size len and calls the passed closure f with a mutable reference to that buffer. The closure should construct a valid network packet (e.g. an ethernet packet) in the buffer. When the closure returns, the transmit buffer is sent out.

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.
