Struct ReturnStmt 

pub struct ReturnStmt { /* private fields */ }

Implementations

impl ReturnStmt

pub fn value(&self) -> Option<SyntaxNode>

The value expression, if any — RETURN_STMT’s only child node. Some/None for both grammars now: the content-ground bare return/return <expr>/return -> x (parser/divert.rs:: return_stmt — the value is optional, and -> x is a distinct RETURN_REDIRECT node, never this accessor’s concern; issue #1973 added the value case, previously always None here) and the code-ground return e?; (B0.8 Wave B tail, issue #1322, parser/stmt.rs::return_stmt — the initializer was already optional there). See syntax_kind.rs’s RETURN_STMT doc for why one node shape serves both grammars.
