Struct WalCeilingPolicy 

pub struct WalCeilingPolicy {
    pub bytes: u64,
    pub source: WalCeilingSource,
}

Resolved WAL-extent policy for one SQLite backend. A zero-byte policy is explicitly disabled; it remains visible in diagnostics and config identity.

Fields

bytes: u64

source: WalCeilingSource

Implementations

impl WalCeilingPolicy

pub fn validate_static( self, file_backed: bool, wal_mode: bool, read_only: bool, ) -> Result<(), SqliteError>

Validate checks that do not need SQLite’s page-size observation. Read-only backends retain configured metadata but enforce no writer policy. Invalid offset arithmetic is rejected in either mode.

pub fn effective_bytes(self, read_only: bool) -> u64

Bytes of writer policy that could be enforced on this backend.
