Trait Implementations

impl Clone for NamedColumnConstraint

fn clone(&self) -> NamedColumnConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NamedColumnConstraint

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

Formats the value using the given formatter.

impl Display for NamedColumnConstraint

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

Formats the value using the given formatter.

impl PartialEq for NamedColumnConstraint

fn eq(&self, other: &NamedColumnConstraint) -> 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 NamedColumnConstraint

fn to_tokens<S: TokenStream + ?Sized, C: ToSqlContext>( &self, s: &mut S, context: &C, ) -> Result<(), S::Error>

Send token(s) to the specified stream with context

fn displayer<'a, 'b, C: ToSqlContext>( &'b self, ctx: &'a C, ) -> SqlDisplayer<'a, 'b, C, Self>

where Self: Sized,
