HttpServiceConnector

rama::http::layer::http_service

Struct HttpServiceConnector

pub struct HttpServiceConnector<S> { /* private fields */ }

Available on crate features http and std only.

Expand description

Discover and select an HTTP service before invoking an inner route connector.

The inner connector honors TargetHttpVersion or rejects unsupported protocols and routes before network I/O with ConnectionErrorDomain::Local and ConnectionErrorKind::Unavailable. Such refusals leave cached endpoint health and the network-attempt budget unchanged; no capability list is needed.

Implementations§

impl<S> HttpServiceConnector<S>

pub fn new(inner: S) -> HttpServiceConnector<S>

pub fn get_ref(&self) -> &S

Gets a reference to the underlying service.

pub fn into_inner(self) -> S

Consumes self, returning the underlying service.

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

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 HttpServiceConnector<S>

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) -> HttpServiceConnector<S>

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 HttpServiceConnector<S>

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

pub fn without_cache(self) -> HttpServiceConnector<S>

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 HttpServiceConnector<S>

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) -> HttpServiceConnector<S>

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 HttpServiceConnector<S>

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>, ) -> HttpServiceConnector<S>

Bound the complete selection operation, including origin fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

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

Bound the complete selection operation, including origin fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn with_timeout(self, timeout: Duration) -> HttpServiceConnector<S>

Bound the complete selection operation, including origin fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn set_timeout(&mut self, timeout: Duration) -> &mut HttpServiceConnector<S>

Bound the complete selection operation, including origin fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn without_timeout(self) -> HttpServiceConnector<S>

Bound the complete selection operation, including origin fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn unset_timeout(&mut self) -> &mut HttpServiceConnector<S>

Bound the complete selection operation, including origin fallback. Disabled by default; the caller’s transport deadlines remain authoritative.

pub fn with_max_candidates(self, count: usize) -> HttpServiceConnector<S>

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 HttpServiceConnector<S>

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) -> HttpServiceConnector<S>

Bound attempts, including the reserved origin fallback attempt.

pub fn set_max_attempts(&mut self, count: usize) -> &mut HttpServiceConnector<S>

Bound attempts, including the reserved origin fallback attempt.
