Enum ForeignKeys 

pub enum ForeignKeys {
    Enforced,
    Unenforced,
}

Whether SQLite enforces declared foreign keys on one connection.

Always written explicitly by the openers that take it, in both directions — the posture must not depend on how the SQLite in use was compiled (this workspace’s vendored build defaults ON, a stock build defaults OFF).

Variants

Enforced

PRAGMA foreign_keys = ON — the origin posture. A write that would leave a dangling reference fails, and declared ON DELETE/ON UPDATE actions run.

The default, matching the vendored build’s compile-time default: a connection that has not thought about this gets the strict answer.

Unenforced

PRAGMA foreign_keys = OFF — the apply posture, for a connection that replays row effects an upstream authority already validated (and whose cascades it already ran, and shipped). See the module docs for why this is correctness, not a relaxation.

Implementations

impl ForeignKeys

pub fn pragma(self) -> &'static str

The pragma statement that puts a connection in this posture.

pub fn is_enforced(self) -> bool

True when SQLite should refuse violating writes on this connection.

Trait Implementations

impl Clone for ForeignKeys

fn clone(&self) -> ForeignKeys

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForeignKeys

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

Formats the value using the given formatter.

impl Default for ForeignKeys

fn default() -> ForeignKeys

Returns the “default value” for a type.

impl PartialEq for ForeignKeys

fn eq(&self, other: &ForeignKeys) -> 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.

impl Copy for ForeignKeys

impl Eq for ForeignKeys

impl StructuralPartialEq for ForeignKeys
