Struct FunctionExpr 

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

Implementations

impl FunctionExpr

pub fn lparen_index(&self) -> Option<usize>

pub fn rparen_index(&self) -> Option<usize>

pub fn params(&self) -> Vec<Param>

Iterate the parameters of the function. Each entry yields the parameter name and the range of its name token. Default-value tokens are skipped (function param defaults are raw tokens in the param list, not nodes).

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

The function body — the expression that follows the ). May be any expression node (a BLOCK_EXPR for function(x) { ... }, or any other expression for function(x) x + 1). Returns None if the body was missing or replaced by an error-recovery placeholder.
