CoalesceOutcome

Enum CoalesceOutcome 

Source
pub enum CoalesceOutcome {
    Lead(CoalesceLead),
    Served(Box<Response<ProxyBody>>),
    Solo,
}
Expand description

What ResponseCache::attach decided for one cache miss (DW-038).

Variants§

§

Lead(CoalesceLead)

This request is the leader: run the fetch, then drop the guard (explicitly after the store stage, or implicitly on panic/cancel) to publish to followers.

§

Served(Box<Response<ProxyBody>>)

A leader’s stored outcome replayed for this follower: serve it exactly like a lookup Serve (the decoration tail still runs; x-cache: hit, Age stamped).

§

Solo

Coalescing made no claim (disabled, map saturated, or the follower fell back): run an independent fetch — the caller’s normal miss path, retries and all.
