Struct PendingEntry 

Source 
struct PendingEntry<B: AbstractTunnelBuilder<R>, R: Runtime> {
    tentative_assignment: Mutex<SupportedTunnelUsage>,
    receiver: Shared<Receiver<Result<<<B as AbstractTunnelBuilder<R>>::Tunnel as AbstractTunnel>::Id>>>,
}
Expand description

An entry for an under-construction in-progress tunnel tracked by an AbstractTunnelMgr.

Fields§

§tentative_assignment: Mutex<SupportedTunnelUsage>

Specification that this tunnel 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 tunnel.

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

§receiver: Shared<Receiver<Result<<<B as AbstractTunnelBuilder<R>>::Tunnel as AbstractTunnel>::Id>>>

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

Implementations§

Source§

impl<B: AbstractTunnelBuilder<R>, R: Runtime> PendingEntry<B, R>

Source

fn new( spec: &SupportedTunnelUsage, ) -> (Self, Sender<Result<<<B as AbstractTunnelBuilder<R>>::Tunnel as AbstractTunnel>::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 tunnel.

Source

fn supports(&self, usage: &TargetTunnelUsage) -> bool

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

Source

fn tentative_restrict_mut(&self, usage: &TargetTunnelUsage) -> Result<()>

Try to change the tentative assignment of this tunnel 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: &TargetTunnelUsage) -> 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.
