Implementations§

impl HttpServiceLayer

pub fn new() -> HttpServiceLayer

pub fn maybe_with_cache(self, cache: Option<AltSvcCache>) -> HttpServiceLayer

Share cached candidates and HTTP/2 frame learning; None disables both. Response observation is composed separately with AltSvcLayer.

pub fn maybe_set_cache( &mut self, cache: Option<AltSvcCache>, ) -> &mut HttpServiceLayer

Share cached candidates and HTTP/2 frame learning; None disables both. Response observation is composed separately with AltSvcLayer.

pub fn with_cache(self, cache: AltSvcCache) -> HttpServiceLayer

Share cached candidates and HTTP/2 frame learning; None disables both. Response observation is composed separately with AltSvcLayer.

pub fn set_cache(&mut self, cache: AltSvcCache) -> &mut HttpServiceLayer

Share cached candidates and HTTP/2 frame learning; None disables both. Response observation is composed separately with AltSvcLayer.

pub fn without_cache(self) -> HttpServiceLayer

Share cached candidates and HTTP/2 frame learning; None disables both. Response observation is composed separately with AltSvcLayer.

pub fn unset_cache(&mut self) -> &mut HttpServiceLayer

Share cached candidates and HTTP/2 frame learning; None disables both. Response observation is composed separately with AltSvcLayer.

pub fn with_attempt_timeout(self, timeout: Duration) -> HttpServiceLayer

Bound one alternative connection attempt, including DNS and handshakes.

Defaults to 300 ms to bound sequential speculation before origin fallback. Increase this for high-latency paths; this connector does not race the origin.

pub fn set_attempt_timeout( &mut self, timeout: Duration, ) -> &mut HttpServiceLayer

Bound one alternative connection attempt, including DNS and handshakes.

Defaults to 300 ms to bound sequential speculation before origin fallback. Increase this for high-latency paths; this connector does not race the origin.

pub fn maybe_with_timeout(self, timeout: Option<Duration>) -> HttpServiceLayer

Bound the entire connection-selection operation, including fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn maybe_set_timeout( &mut self, timeout: Option<Duration>, ) -> &mut HttpServiceLayer

Bound the entire connection-selection operation, including fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn with_timeout(self, timeout: Duration) -> HttpServiceLayer

Bound the entire connection-selection operation, including fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn set_timeout(&mut self, timeout: Duration) -> &mut HttpServiceLayer

Bound the entire connection-selection operation, including fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn without_timeout(self) -> HttpServiceLayer

Bound the entire connection-selection operation, including fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn unset_timeout(&mut self) -> &mut HttpServiceLayer

Bound the entire connection-selection operation, including fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn with_max_candidates(self, count: usize) -> HttpServiceLayer

Bound inspected candidates, including unknown or unsupported protocols.

Defaults to 16, matching the cache’s default advertisement capacity. Zero bypasses alternatives. Local capability refusals do not consume max_attempts, so this separately bounds caller-supplied candidate lists.

pub fn set_max_candidates(&mut self, count: usize) -> &mut HttpServiceLayer

Bound inspected candidates, including unknown or unsupported protocols.

Defaults to 16, matching the cache’s default advertisement capacity. Zero bypasses alternatives. Local capability refusals do not consume max_attempts, so this separately bounds caller-supplied candidate lists.

pub fn with_max_attempts(self, count: usize) -> HttpServiceLayer

Bound connection attempts, reserving one for ordinary origin fallback. Zero rejects the operation without invoking the inner connector.

pub fn set_max_attempts(&mut self, count: usize) -> &mut HttpServiceLayer

Bound connection attempts, reserving one for ordinary origin fallback. Zero rejects the operation without invoking the inner connector.
