Enum Phase 

#[non_exhaustive]
pub enum Phase {
    SlowStart,
    CongestionAvoidance,
}

FileCC algorithm phase (specs/rules/srt-congestion.md rules 4-5). Slow Start (§5.2.1.1) runs exactly once at the start of a connection; it transitions to Congestion Avoidance (§5.2.1.2) on the first loss, CWND_SIZE exceeding its maximum, or a timeout — and never transitions back (L3323-3326).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SlowStart

§5.2.1.1 — probes for available bandwidth; runs exactly once.

CongestionAvoidance

§5.2.1.2 — entered once slow start ends; the steady-state AIMD phase.
