Enum rustc_ast::ast::FnRetTy

pub enum FnRetTy {
    Default(Span),
    Ty(P<Ty>),
}

Variants

Default(Span)

Returns 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.

Implementations

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
