Enum SegmentEnd 

pub enum SegmentEnd {
    Marker,
    ZeroHeader,
    Exhausted,
    TornTail {
        reason: &'static str,
    },
    Corrupt {
        reason: &'static str,
        committed_at: Option<usize>,
    },
}

Why the walk over a segment stopped.

Variants

Marker

A 16-byte end-of-log marker follows the last frame.

ZeroHeader

An all-zero header follows the last frame (stores written before the marker).

Exhausted

Fewer than 16 bytes remain after the last frame.

TornTail

A frame fails its checks and nothing committed follows it: an append the crash interrupted. The engine truncates the log there on open (final segment only).

Fields

reason: &'static str

Corrupt

A frame fails its checks and committed data follows it (or it sits in a segment that was complete): damage inside committed data. The engine refuses to open.

Fields

reason: &'static str

committed_at: Option<usize>

Offset of the committed data found after the damage, if any.
