Struct ConstraintDef 

pub struct ConstraintDef {
    pub name: Box<str>,
    pub data: ConstraintData,
}

A constraint definition attached to a table.

Fields

name: Box<str>

The name of the constraint. Unique within the containing ModuleDef.

data: ConstraintData

The data for the constraint.

Trait Implementations

impl Clone for ConstraintDef

fn clone(&self) -> ConstraintDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintDef

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

Formats the value using the given formatter.

impl From<ConstraintDef> for RawConstraintDefV9

fn from(val: ConstraintDef) -> Self

Converts to this type from the input type.

impl ModuleDefLookup for ConstraintDef

type Key<'a> = &'a str

A reference to a definition of this type within a module def. This reference should be portable across migrations.

fn key(&self) -> Self::Key<'_>

Get a reference to this definition.

fn lookup<'a>(module_def: &'a ModuleDef, key: Self::Key<'_>) -> Option<&'a Self>

Look up this entity in the module def.

impl PartialEq for ConstraintDef

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