tor_cell::chancell::msg

Struct Relay 

Source 
pub struct Relay { /* private fields */ }
Expand description

A Relay cell - that is, one transmitted over a circuit.

Once a circuit has been established, relay cells can be sent over it. Clients can send relay cells to any relay on the circuit. Any relay on the circuit can send relay cells to the client, either directly (if it is the first hop), or indirectly through the intermediate hops.

A different protocol is defined over the relay cells; it is implemented in the crate::relaycell module.
