Enum syntax::ast::FunctionRetTy

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

Unstable (rustc_private)

Variants

None(Span)

Unstable (rustc_private)

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

Default(Span)

Unstable (rustc_private)

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>)

Unstable (rustc_private)
