Expand description

A token to transmit a single network packet.

Required Methods§

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.

The timestamp must be a number of milliseconds, monotonically increasing since an arbitrary moment in time, such as system startup.
