Trait Implementations

impl Clone for TableConstraint

fn clone(&self) -> TableConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableConstraint

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

Formats the value using the given formatter.

impl PartialEq for TableConstraint

fn eq(&self, other: &TableConstraint) -> 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 ToTokens for TableConstraint

fn to_tokens<S: TokenStream>(&self, s: &mut S) -> Result<(), S::Error>

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

impl Eq for TableConstraint

impl StructuralPartialEq for TableConstraint
