Struct AssignmentExpr 

pub struct AssignmentExpr(/* private fields */);

Implementations

impl AssignmentExpr

pub fn op_kind(&self) -> Option<SyntaxKind>

The assignment operator kind. Returns one of ASSIGN_LEFT (<-), ASSIGN_RIGHT (->), SUPER_ASSIGN (<<-), SUPER_ASSIGN_RIGHT (->>), ASSIGN_EQ (=), or WALRUS (:=).

pub fn op_token(&self) -> Option<SyntaxToken<RLanguage>>

The operator token, if present.

pub fn target_element(&self) -> Option<SyntaxElement<RLanguage>>

The element on the target side of the operator (the side that becomes the binding). For <-/=/<<-/:= this is the left element; for ->/->> it is the right element.

pub fn value_element(&self) -> Option<SyntaxElement<RLanguage>>

The element on the value side of the operator.

pub fn target_name(&self) -> Option<SmolStr>

If the target is a simple IDENT (or backtick-quoted identifier), the bound name as a SmolStr. Returns None for complex LHS like dim(x) <- ..., x[1] <- ..., x$y <- ....

pub fn target_name_token(&self) -> Option<SyntaxToken<RLanguage>>

The target name token, useful when the binding site’s range is needed.
