Trait Implementations

impl Clone for Update

fn clone(&self) -> Update

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Update

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

Formats the value using the given formatter.

impl From<Update> for ExprSet

fn from(value: Update) -> ExprSet

Converts to this type from the input type.

impl<'a, T> IntoExprTarget<'a, T> for &'a Update

where T: Resolve,

fn into_expr_target(self, schema: &'a T) -> ExprTarget<'a>

impl Node for Update

fn visit<V>(&self, visit: V)

where V: Visit,

fn visit_mut<V>(&mut self, visit: V)

where V: VisitMut,

impl PartialEq for Update

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