Struct TableConstraints 

pub struct TableConstraints {
    pub uniques: Vec<UniqueConstraint>,
    pub foreign_keys: Vec<ForeignKey>,
    pub checks: Vec<CheckConstraint>,
}

A declarative constraint set attached to a table’s schema. Empty by default.

Fields

uniques: Vec<UniqueConstraint>

foreign_keys: Vec<ForeignKey>

checks: Vec<CheckConstraint>

Implementations

impl TableConstraints

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for TableConstraints

fn clone(&self) -> TableConstraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableConstraints

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

Formats the value using the given formatter.

impl Default for TableConstraints

fn default() -> TableConstraints

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TableConstraints

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TableConstraints

fn eq(&self, other: &TableConstraints) -> 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 Serialize for TableConstraints

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
