Enum WalValidationError 

pub enum WalValidationError {
    BadMagic,
    PageSizeMismatch {
        db: u32,
        wal: u32,
    },
    Header(Error),
}

A WAL that cannot be admitted to the timeline at all (physical-validation hard stops). Distinct from “no committed snapshot”, which is a valid empty timeline.

Variants

BadMagic

The -wal is shorter than its 32-byte header, or carries the wrong magic.

PageSizeMismatch

The WAL header’s page size disagrees with the DB header’s — a HARD STOP, since every frame would be mis-sliced. db and wal are the two declared sizes.

Fields

db: u32

wal: u32

Header(Error)

The main database header itself failed to parse.
