Crate tor_hsclient 

tor-hsclient

Core implementation for onion services client.

This crate creates circuits to onion circuits, retains them for reuse, and hands them out as appropriate. It is also responsible for maintaining all relevant state about hidden services, and their descriptors and introduction points.

Modules

connect 🔒

Main implementation of the connection functionality

err 🔒

Errors relating to being a hidden service client

isol_map 🔒

Data structure MultikeyIsolatedMap indexed by multiple keys and an isolation

keys 🔒

Hidden service (onion service) client key management functionality

pow 🔒

Common support for proof of work denial of service mitigation on the client side

proto_oneshot 🔒

[oneshot] channel between a circuit control message handler and the main code

relay_info 🔒

Translate relay information from the formats used in the onion service protocol into CircTargets that we can use for building circuits.

state 🔒

Implement a cache for onion descriptors and the facility to remember a bit about onion service history.
