Struct CommitId 

pub struct CommitId {
    pub segment: WalSegmentId,
    pub commit_frame_index: usize,
    pub db_size_after_commit: u32,
}

Address of a materializable database state: the replay of all valid frames up to a COMMIT frame. CommitId = (segment, commit_frame_index, db_size_after_commit).

Fields

segment: WalSegmentId

The salt segment this commit belongs to.

commit_frame_index: usize

0-based file-order index of the COMMIT frame within the segment.

db_size_after_commit: u32

db_size_after_commit recorded in the COMMIT frame header — the database’s page count once this commit is materialized.
