Enum ChannelUsage

Source 
#[non_exhaustive]
pub enum ChannelUsage {
    Dir,
    UserTraffic,
    UselessCircuit,
}
Expand description

The usage that we have in mind when requesting a channel.

A channel may be used in multiple ways. Each time a channel is requested from ChanMgr a separate ChannelUsage is passed in to tell the ChanMgr how the channel will be used this time.

To be clear, the ChannelUsage is aspect of a request for a channel, and is not an immutable property of the channel itself.

This type is obtained from a tor_circmgr::usage::SupportedCircUsage in tor_circmgr::usage, and it has roughly the same set of variants.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Dir

Requesting a channel to use for BEGINDIR-based non-anonymous directory connections.

§

UserTraffic

Requesting a channel to transmit user traffic (including exit traffic) over the network.

This includes the case where we are constructing a circuit preemptively, and planning to use it for user traffic later on.

§

UselessCircuit

Requesting a channel that the caller does not plan to used at all, or which it plans to use only for testing circuits.
