Implementations§

§

impl OptionsCacheConfig

pub const fn new() -> OptionsCacheConfig

Create the RFC-preserving cache policy.

pub const fn with_max_entries(self, max_entries: usize) -> OptionsCacheConfig

Set the bounded number of service-policy entries.

pub fn set_max_entries(&mut self, max_entries: usize) -> &mut OptionsCacheConfig

Set the bounded number of service-policy entries.

pub const fn with_max_in_flight( self, max_in_flight: usize, ) -> OptionsCacheConfig

Set the number of distinct concurrent OPTIONS exchanges.

pub fn set_max_in_flight( &mut self, max_in_flight: usize, ) -> &mut OptionsCacheConfig

Set the number of distinct concurrent OPTIONS exchanges.

pub const fn with_missing_ttl(self, ttl: Option<Duration>) -> OptionsCacheConfig

Override the RFC’s non-expiring default for a missing Options-TTL.

pub fn set_missing_ttl( &mut self, ttl: Option<Duration>, ) -> &mut OptionsCacheConfig

Override the RFC’s non-expiring default for a missing Options-TTL.

pub const fn with_max_ttl(self, ttl: Option<Duration>) -> OptionsCacheConfig

Clamp a peer-supplied Options-TTL.

pub fn set_max_ttl(&mut self, ttl: Option<Duration>) -> &mut OptionsCacheConfig

Clamp a peer-supplied Options-TTL.

pub const fn with_stale_if_error( self, duration: Option<Duration>, ) -> OptionsCacheConfig

Permit an expired snapshot during refresh and after failure.

The duration is measured from normal expiry. The default is None, so an expired snapshot is never served.

pub fn set_stale_if_error( &mut self, duration: Option<Duration>, ) -> &mut OptionsCacheConfig

Permit an expired snapshot during refresh and after failure.

The duration is measured from normal expiry. The default is None, so an expired snapshot is never served.

pub const fn with_failure_backoff( self, duration: Duration, ) -> OptionsCacheConfig

Suppress repeated refresh attempts after one completed failure.

pub fn set_failure_backoff( &mut self, duration: Duration, ) -> &mut OptionsCacheConfig

Suppress repeated refresh attempts after one completed failure.

pub const fn max_entries(&self) -> usize

Return the maximum entry count.

pub const fn max_in_flight(&self) -> usize

Return the maximum distinct concurrent OPTIONS exchanges.

pub const fn missing_ttl(&self) -> Option<Duration>

Return the local lifetime for a missing peer TTL.

pub const fn max_ttl(&self) -> Option<Duration>

Return the maximum accepted peer TTL.

pub const fn stale_if_error(&self) -> Option<Duration>

Return the bounded stale-on-error horizon.

pub const fn failure_backoff(&self) -> Duration

Return the completed-refresh failure backoff.
