Struct HsPowClient

Source 
pub(crate) struct HsPowClient {
    v1: Option<HsPowClientV1>,
}
Expand description

Client-side state for a series of connection attempts that might use proof-of-work.

The HsPowClient can be initialized using a recent HsDesc, at which point we choose a proof of work scheme and its initial parameters.

When an attempt fails, we can increase the effort in an algorithm-specific way.

For now we have only scheme, v1. We try to make only minimal assumptions about how future schemes may interact with each other.

Fields§

§v1: Option<HsPowClientV1>

Client state specifically for the v1 scheme

Implementations§

Source§

impl HsPowClient

Source

pub(crate) fn new(hs_blind_id: &HsBlindId, desc: &HsDesc) -> Self

Initialize a new group of connection attempts, given the required context

Source

pub(crate) fn increase_effort(&mut self)

Increase effort in response to a failed connection attempt.

If no proof of work scheme is in use or the effort cannot be increased, this has no effect.

Specified in https://spec.torproject.org/hspow-spec/common-protocol.html#client-timeout

Source

pub(crate) async fn solve( &self, ) -> Result<Option<ProofOfWork>, ProofOfWorkError>

If we have an applicable proof of work scheme, do the work and return a proof
