Trait Implementations

impl AsRef<ExprIR> for ExprIR

fn as_ref(&self) -> &ExprIR

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<Node> for ExprIR

fn borrow(&self) -> &Node

Immutably borrows from an owned value.

impl Clone for ExprIR

fn clone(&self) -> ExprIR

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExprIR

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

Formats the value using the given formatter.

impl From<&ExprIR> for Node

fn from(value: &ExprIR) -> Self

Converts to this type from the input type.

impl PartialEq for ExprIR

fn eq(&self, other: &ExprIR) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for ExprIR

impl StructuralPartialEq for ExprIR
