Pager

The pager interface implements the persistence layer by providing access to pages of the database file, including caching, concurrency control, and transaction management.

PlatformIO

QueryRunner

Statement

SymbolTable

SyscallIO

WalFile

WalFileShared

WalFileShared is the part of a WAL that will be shared between threads. A wal has information that needs to be communicated between threads so this struct does the job.

Enums

CheckpointMode

CheckpointStatus

Completion

LimboError

PagerCacheflushStatus

The status of the current cache flush. A Done state means that the WAL was committed to disk and fsynced, plus potentially checkpointed to the DB (and the DB then fsynced).

Statics

DatabaseStorage

DatabaseStorage is an interface a database file that consists of pages.

Write-ahead log (WAL).
