Enum LinkSelection 

pub enum LinkSelection {
    Auto,
    FirstSuccess,
    Random,
}

How Pool::call/Pool::publish order the pool’s currently-connected links before applying their own existing first-match/replication_factor logic — changes ORDER only, never how many links get used. Matches macula_client.erl’s own link_selection option (first_success/ random) and macula-go/macula-dotnet’s identically-named enum, so config ported from any of those doesn’t need re-learning.

Variants

Auto

(The default.) Derives the actual policy from StationDiscoveryOptions::enabled: FirstSuccess if discovery is off (this pool’s original, only behavior, unchanged), Random if it’s on.

FirstSuccess

Tries links in Seed-list order (bootstrap seeds in the order the caller gave them, then discovered links in discovery order) — this pool’s baseline behavior, since links is a plain append-only Vec (see Pool’s own doc on why that, not a HashMap, is the backing store — insertion order is the ordering, nothing extra to track).

Random

Uniformly shuffles the connected-links list before the same first-match (Call) or take-first-N (Publish) logic runs. Composes safely with a small replication_factor: shuffling ahead of a 1-element slice is a no-op.
