Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl HasDesc for Expr

fn desc(&self) -> &'static str

Obtain a human-readable descriptive name for this node.

fn desc_full(&self) -> String

Obtain a human-readable description for this node, possibly containing the node’s name.

impl HasSpan for Expr

fn span(&self) -> Span

Obtain the full span of the input file that this node covers.

fn human_span(&self) -> Span

Obtain a span which can be used to refer to this node in error messages presented to humans. This will generally be the name for things like entities, processes, and variables. Defaults to return whatever span() returns.

impl PartialEq for Expr

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