Enum CacheLeg 

enum CacheLeg<T> {
    Ready(Result<T, RepoError>),
    Slow(JoinHandle<Result<T, RepoError>>),
}

The cache side of a cache-first query.

Either the cache answered inside the fast path, or it is still working and the query can be collected later. Keeping the slow case addressable rather than discarding it is what lets an offline query fall back to cached content after the server leg fails.

TRACES: UR-002 | DR-013

Variants

Ready(Result<T, RepoError>)

The cache answered within HybridRepository::CACHE_FAST_PATH.

Slow(JoinHandle<Result<T, RepoError>>)

Still running. Awaiting the handle yields the answer eventually.

Implementations

impl<T> CacheLeg<T>

fn split( self, ) -> (Option<Result<T, RepoError>>, Option<JoinHandle<Result<T, RepoError>>>)

Split into the fast-path answer and the still-running query. Exactly one side is Some.
