    pub value: Cow<'static, str>,
}

value: Cow<'static, str>

Check expression

Implementations

impl CheckConstraint

pub fn new( table: impl Into<Cow<'static, str>>, name: impl Into<Cow<'static, str>>, value: impl Into<Cow<'static, str>>, ) -> Self

Create a new check constraint

pub fn name(&self) -> &str

Get the constraint name

pub fn table(&self) -> &str

Get the table name

impl CheckConstraint

pub fn to_constraint_sql(&self) -> String

Generate the CHECK constraint clause

Trait Implementations

impl Clone for CheckConstraint

fn clone(&self) -> CheckConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckConstraint

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

Formats the value using the given formatter.

impl Default for CheckConstraint

fn default() -> Self

Returns the “default value” for a type.

impl From<CheckConstraintDef> for CheckConstraint

fn from(def: CheckConstraintDef) -> Self

Converts to this type from the input type.

impl PartialEq for CheckConstraint

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