Struct Footer

pub struct Footer {
    pub generation: u64,
    pub index_offset: u64,
    pub schema_offset: u64,
    pub schema_len: u32,
    pub record_count: u32,
    pub file_len: u64,
    pub next_record_id: u64,
}

Expand description

A parsed footer — the authoritative statement of a file’s committed state.

Fields§

§generation: u64

Monotonic commit counter, starting at 1.

§index_offset: u64§schema_offset: u64§schema_len: u32§record_count: u32§file_len: u64

Committed extent. Bytes at or beyond this are uncommitted debris.

§next_record_id: u64

The id the next appended record will take. Persisted rather than derived from the index, so removing the highest-id record cannot cause an id to be handed out twice.
