Enum UploadSessionLifecycle 

pub enum UploadSessionLifecycle {
    Open {
        expires_at_ms: u64,
    },
    Completed {
        completed_at_ms: u64,
        content_ref: ContentRef,
    },
    Aborted {
        aborted_at_ms: u64,
    },
}

Monotonic lifecycle of a durable upload session.

A session starts open and ends either completed or aborted. The compare-and-swap that writes the terminal state decides which transition won; provider cleanup happens afterward. Terminal sessions never reopen, so another attempt requires a new session and content id.

Variants

Open

The one state that may stage bytes and complete. Live until its lease passes, after which garbage collection aborts it.

Fields

expires_at_ms: u64

Unix-millisecond instant after which the session is abandoned. The record carries it so no session transition depends on an object’s provider timestamp.

Completed

Terminal: the content is durable and verified. This is the only state a receipt may be minted from, and the content reference it carries is what every re-mint and idempotent completion retry answers with.

Fields

completed_at_ms: u64

Unix-millisecond stamp written by the completing compare-and-swap, and the only input to when the content may be reclaimed.

content_ref: ContentRef

Verified immutable content this session settled on, and the one place a completed session’s reference exists.

Aborted

Terminal: the session will never select content. Its content identity was never published — a receipt exists only for a completed session — so the object it named belongs to nobody and is deleted.

Fields

aborted_at_ms: u64

Unix-millisecond stamp written by the aborting compare-and-swap, and the only input to when the record may be deleted.
