Struct WalGenerationIdentity 

pub struct WalGenerationIdentity {
    pub checkpoint_seq: u32,
    pub salts: WalSalts,
}

Identity for one WAL generation.

A generation changes whenever the WAL header is reset for a new checkpoint epoch. Salts usually change too, but correctness must not rely on that: reset/ABA detection must still work if a caller reuses the same salt pair with a new checkpoint sequence.

Fields

checkpoint_seq: u32

Checkpoint sequence stored in the WAL header.

salts: WalSalts

Salt pair copied into WAL frames for this generation.
