Enum ConstraintEnforcementMode 

pub enum ConstraintEnforcementMode {
    Immediate,
    Deferred,
}

Controls when constraint validation occurs for new writes.

Variants

Immediate

Perform all constraint checks before rows become visible.

Deferred

Defer checks so callers can load data quickly and validate later.

Implementations

impl ConstraintEnforcementMode

pub const fn is_immediate(self) -> bool

pub const fn is_deferred(self) -> bool

Trait Implementations

impl Clone for ConstraintEnforcementMode

fn clone(&self) -> ConstraintEnforcementMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintEnforcementMode

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

Formats the value using the given formatter.

impl Default for ConstraintEnforcementMode

fn default() -> ConstraintEnforcementMode

Returns the “default value” for a type.

impl PartialEq for ConstraintEnforcementMode

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