SessionState

Enum SessionState 

Source 
#[non_exhaustive]
#[repr(u8)]
pub enum SessionState {
    Open = 0,
    Draining = 1,
    Sealed = 2,
    Complete = 3,
}
Expand description

The session lifecycle chain, held in one AtomicU8 and advanced only through CAS transitions that name their expected source state — illegal transitions become impossible rather than untested.

Two flags deliberately stay OUTSIDE the chain (mirroring the S2 plan’s admission_open exception): capture_failed and promoted are orthogonal properties, not chain positions — a capture-failed session still seals and completes (the capture-failed seal path), and promotion happens to already- complete sessions. Folding them in would multiply states for combinations that all remain reachable.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Open = 0

Admitting requests.

§

Draining = 1

try_close claimed the close; streams may still be draining. A failed finalize returns to Open via reset_close.

§

Sealed = 2

The receipt/ATIF artifact is durably committed; the fallible close tail (bridge emit + journal removal) is still pending.

§

Complete = 3

The close ran to full completion; the registry may evict.
