Struct Param 

pub struct Param { /* private fields */ }

Implementations

impl Param

pub fn name_token(&self) -> Option<SyntaxToken>

pub fn is_ref(&self) -> bool

true if this parameter is ref-marked. Always false for a lambda parameter — ref captures don’t exist (RULED 2026-07-23) and parser/expr.rs::lambda_param never accepts the keyword.

pub fn type_annotation(&self) -> Option<TypeAnnotation>

The parameter’s : type annotation, if written (NG-A, #1487).
