SQLite Documentation

Variants

Delete

Delete journal file after each transaction

Example

assert_eq!(JournalMode::Delete.to_sql().sql(), "DELETE");

Truncate

Truncate journal file after each transaction

Example

assert_eq!(JournalMode::Truncate.to_sql().sql(), "TRUNCATE");

Persist

Keep journal file persistent

Example

assert_eq!(JournalMode::Persist.to_sql().sql(), "PERSIST");

Memory

Store journal in memory

Example

assert_eq!(JournalMode::Memory.to_sql().sql(), "MEMORY");

Wal

Write-Ahead Logging mode

Example

assert_eq!(JournalMode::Wal.to_sql().sql(), "WAL");

Off

Disable journaling

Example

assert_eq!(JournalMode::Off.to_sql().sql(), "OFF");

Trait Implementations

impl Clone for JournalMode

fn clone(&self) -> JournalMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JournalMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for JournalMode

fn eq(&self, other: &JournalMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
