Trait Implementations

impl<'bump> Debug for TableConstraint<'bump>

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

Formats the value using the given formatter.

impl<'bump> Eq for TableConstraint<'bump>

impl<'bump> PartialEq for TableConstraint<'bump>

fn eq(&self, other: &TableConstraint<'bump>) -> 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<'bump> StructuralPartialEq for TableConstraint<'bump>

impl ToTokens for TableConstraint<'_>

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

Send token(s) to the specified stream

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

Format AST node
