Struct ServiceCapabilities 

pub struct ServiceCapabilities { /* private fields */ }

Available on crate features icap and std only.

Immutable capabilities discovered with one successful OPTIONS exchange.

Implementations

impl ServiceCapabilities

pub fn from_options_response( response: Response, opt_body: Option<Bytes>, max_headers: usize, allow_206_offered: bool, validation: OptionsValidation, ) -> Result<ServiceCapabilities, CapabilitiesError>

Parse a completed OPTIONS response into a capability snapshot.

max_headers bounds temporary header slots. allow_206_offered must reflect the corresponding OPTIONS request; an unsolicited response token is retained in the raw response but does not negotiate 206.

pub const fn response(&self) -> &Response

Return the accepted raw OPTIONS response metadata.

pub const fn methods(&self) -> &SupportedMethods

Return parsed method support.

pub const fn service_tag(&self) -> Option<&Bytes>

Return the service generation tag, including its wire quoting.

pub const fn service(&self) -> Option<&Bytes>

Return the human-readable service description.

pub const fn service_id(&self) -> Option<&Bytes>

Return the opaque service identifier.

pub const fn preview(&self) -> Option<Preview>

Return the maximum Preview size advertised by the service.

pub fn allows_204(&self) -> bool

Return whether the service advertises 204 support.

pub const fn allows_206(&self) -> bool

Return whether the service negotiated 206 support.

A response token alone is insufficient: this is true only when the corresponding OPTIONS request offered the extension.

pub const fn allowed_features(&self) -> &AllowedFeatures

Return every valid feature token advertised in Allow.

pub fn allows_icap_trailers(&self) -> bool

Return whether the service advertises negotiated outer ICAP trailers.

pub const fn transfer_rules(&self) -> &TransferRules

Return deterministic transfer selection rules.

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

Return the valid peer-supplied OPTIONS lifetime.

None means the RFC’s non-expiring default or an invalid field. Cache policy distinguishes those cases internally and never treats an invalid value as non-expiring.

pub const fn max_connections(&self) -> Option<u64>

Return the advertised connection limit.

pub const fn date(&self) -> Option<&Bytes>

Return the opaque server date value.

pub const fn opt_body_type(&self) -> Option<&Bytes>

Return the declared type of the optional OPTIONS body.

pub const fn opt_body(&self) -> Option<&Bytes>

Return the bounded, opaque OPTIONS body.
