Struct Padding

Source 
#[non_exhaustive]
pub struct Padding {}
Expand description

A Padding message is a fixed-length message on a channel that is ignored.

Padding message can be used to disguise the true amount of data on a channel, or as a “keep-alive”.

The correct response to a padding cell is to drop it and do nothing.
