Enum syntex_syntax::ast::FunctionRetTy

pub enum FunctionRetTy {
    NoReturn(Span),
    DefaultReturn(Span),
    Return(P<Ty>),
}

Variants

NoReturn	Functions with return type !that always raise an error or exit (i.e. never return to the caller)
DefaultReturn	Return type is not specified. Functions default to () and closures default to inference. Span points to where return type would be inserted.
Return	Everything else

Methods

impl FunctionRetTy

fn span(&self) -> Span
