HttpServiceCandidates

rama::http::conn

Struct HttpServiceCandidates 

pub struct HttpServiceCandidates { /* private fields */ }
Available on crate features http and std only.
Expand description

An immutable, ordered discovery snapshot for one origin.

Share snapshots through Arc<HttpServiceCandidates>, including the Arc already provided by request extensions. Discovery-specific freshness and availability remain with the source; inspect those before trying a candidate.

Implementations§

§

impl HttpServiceCandidates

pub fn new( origin: HttpOrigin, candidates: impl Into<Box<[HttpServiceCandidate]>>, ) -> HttpServiceCandidates

Create a new discovery snapshot in preference order.

pub fn origin(&self) -> &HttpOrigin

The origin all candidates serve.

pub fn iter(&self) -> Iter<'_, HttpServiceCandidate> ⓘ

Candidates in source preference order.

pub fn get(&self, index: usize) -> Option<&HttpServiceCandidate>

Candidate at the given stable snapshot index.

pub fn len(&self) -> usize

Number of advertised candidates, including any since expired or suppressed.

pub fn is_empty(&self) -> bool

Whether this snapshot has no candidates.
