Trait smoltcp::phy::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) -> Rwhere
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.
