Struct tor_circmgr::mgr::PendingEntry

source · 
struct PendingEntry<B: AbstractCircBuilder> {
    tentative_assignment: Mutex<B::Spec>,
    receiver: Shared<Receiver<Result<<<B as AbstractCircBuilder>::Circ as AbstractCirc>::Id>>>,
}
Expand description

An entry for an under-construction in-progress circuit tracked by an AbstractCircMgr.

Fields§

§tentative_assignment: Mutex<B::Spec>

Specification that this circuit will support, if every pending request that is waiting for it is attached to it.

This spec becomes more and more restricted as more pending requests are waiting for this circuit.

This spec is contained by circ_spec, and must support the usage of every pending request that’s waiting for this circuit.

§receiver: Shared<Receiver<Result<<<B as AbstractCircBuilder>::Circ as AbstractCirc>::Id>>>

A shared future for requests to use when waiting for notification of this circuit’s success.

Implementations§

source§

impl<B: AbstractCircBuilder> PendingEntry<B>

source

fn new( circ_spec: &B::Spec ) -> (Self, Sender<Result<<<B as AbstractCircBuilder>::Circ as AbstractCirc>::Id>>)

Make a new PendingEntry that starts out supporting a given spec. Return that PendingEntry, along with a Sender to use to report the result of building this circuit.

source

fn supports(&self, usage: &<B::Spec as AbstractSpec>::Usage) -> bool

Return true if this circuit’s current tentative assignment supports usage.

source

fn tentative_restrict_mut( &self, usage: &<B::Spec as AbstractSpec>::Usage ) -> Result<()>

Try to change the tentative assignment of this circuit by restricting it for use with usage.

Return an error if the current tentative assignment didn’t support usage in the first place.

source

fn find_best( ents: &[Arc<Self>], usage: &<B::Spec as AbstractSpec>::Usage ) -> Vec<Arc<Self>>

Find the best PendingEntry values from a slice for use with usage.

§Requirements

The ents slice must not be empty. Every element of ents must support the given spec.
