Struct tor_circmgr::mgr::OpenEntry
source · pub(crate) struct OpenEntry<S, C> {
spec: S,
circ: Arc<C>,
expiration: ExpirationInfo,
}
Expand description
An entry for an open circuit held by an AbstractCircMgr
.
Fields§
§spec: S
Current AbstractCircSpec for this circuit’s permitted usages.
circ: Arc<C>
The circuit under management.
expiration: ExpirationInfo
When does this circuit expire?
(Note that expired circuits are removed from the manager, which does not actually close them until there are no more references to them.)
Implementations§
source§impl<S: AbstractSpec, C: AbstractCirc> OpenEntry<S, C>
impl<S: AbstractSpec, C: AbstractCirc> OpenEntry<S, C>
sourcefn new(spec: S, circ: Arc<C>, expiration: ExpirationInfo) -> Self
fn new(spec: S, circ: Arc<C>, expiration: ExpirationInfo) -> Self
Make a new OpenEntry for a given circuit and spec.
sourcefn supports(&self, usage: &<S as AbstractSpec>::Usage) -> bool
fn supports(&self, usage: &<S as AbstractSpec>::Usage) -> bool
Return true if this circuit can be used for usage
.
sourcefn restrict_mut(
&mut self,
usage: &<S as AbstractSpec>::Usage,
now: Instant
) -> Result<()>
fn restrict_mut( &mut self, usage: &<S as AbstractSpec>::Usage, now: Instant ) -> Result<()>
Change this circuit’s permissible usage, based on its having
been used for usage
at time now
.
Return an error if this circuit may not be used for usage
.
sourcefn find_best<'a>(
ents: &'a mut [&'a mut Self],
usage: &<S as AbstractSpec>::Usage,
parallelism: usize
) -> &'a mut Self
fn find_best<'a>( ents: &'a mut [&'a mut Self], usage: &<S as AbstractSpec>::Usage, parallelism: usize ) -> &'a mut Self
Find the “best” entry from a slice of OpenEntry for supporting
a given usage
.
If parallelism
is some N greater than 1, we pick randomly
from the best N
circuits.
§Requirements
Requires that ents
is nonempty, and that every element of ents
supports spec
.
sourcefn should_expire(&self, unused_cutoff: Instant, dirty_cutoff: Instant) -> bool
fn should_expire(&self, unused_cutoff: Instant, dirty_cutoff: Instant) -> bool
Return true if this circuit has been marked as dirty before
dirty_cutoff
, or if it is an unused circuit set to expire before
unused_cutoff
.
