Enum syntex_syntax::ast::FunctionRetTy

pub enum FunctionRetTy {
    None(Span),
    Default(Span),
    Ty(P<Ty>),
}

Variants

None(Span)

Functions with return type !that always raise an error or exit (i.e. never return to the caller)

Default(Span)

Return type is not specified.

Functions default to () and closures default to inference. Span points to where return type would be inserted.

Ty(P<Ty>)

Everything else
