Enum ReleaseReason 

#[non_exhaustive]
pub enum ReleaseReason {
    Retired,
    CommitFailed,
    TestOnly,
    Drained,
}

Why a set of buffers is being handed back.

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.

Retired

They stopped being scanned out: a later commit’s flip completed.

The ordinary path, and the one invariant 1 governs.

CommitFailed

The commit that would have shown them was rejected.

Invariant 2: no flip is in flight to gate them on, so they go back at once and the producer can reuse them immediately.

TestOnly

A test commit, which applies nothing to hardware.

Drained

The scene is being torn down, paused, or rebound.
