Variants

Literal(Literal)

Path(Vec<String>)

Dotted path segments, already split: "foo.bar.baz" → vec!["foo", "bar", "baz"].

Not(Box<Spanned<Expr>>)

BinOp(BinOp, Box<Spanned<Expr>>, Box<Spanned<Expr>>)

Ternary(Box<Spanned<Expr>>, Box<Spanned<Expr>>, Box<Spanned<Expr>>)

Call(String, Vec<Spanned<Expr>>)

ident(arg, arg, ...) — invokes a handler on the scope. RFC-024. Handlers resolve via invoke_handler; the name is a single identifier, not a path.

Assign(Vec<String>, Box<Spanned<Expr>>)

path = expr — writes expr through the scope proxy’s set trap at path. RFC-024. path is one or more dotted identifiers.

Seq(Vec<Spanned<Expr>>)

a; b; c — evaluated left-to-right; result is the last statement’s value. RFC-024. Top-level form for pp-on values containing multiple statements.

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.
