Enum HaltReason 

pub enum HaltReason {
    BackpressureStall {
        stalled_for: Duration,
        threshold: Duration,
    },
    BackendDisk(String),
    BackendCorrupted(String),
    BackendError(String),
}

Reason a writer requested kernel halt.

Variants

BackpressureStall

A submit blocked longer than the configured halt threshold while waiting for the writer thread to drain the channel.

Fields

stalled_for: Duration

How long the submit blocked before signaling halt.

threshold: Duration

The configured threshold the stall exceeded.

BackendDisk(String)

The backend rejected a commit because of disk pressure (ENOSPC, RLIMIT_FSIZE, quota). The audit contract requires fail-stop rather than dropping entries.

BackendCorrupted(String)

The backend reported structural corruption.

BackendError(String)

The backend returned an unclassified error that the writer cannot retry past.
