Enum rustc_ast::ast::SelfKind

pub enum SelfKind {
    Value(Mutability),
    Region(Option<Lifetime>, Mutability),
    Explicit(P<Ty>, Mutability),
}

Alternative representation for Args describing self parameter of methods.

E.g., &mut self as in fn foo(&mut self).

Trait Implementations

impl Clone for SelfKind

fn clone(&self) -> SelfKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SelfKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl<__D: Decoder> Decodable<__D> for SelfKind

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

impl<__E: Encoder> Encodable<__E> for SelfKind

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

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.
