Struct rustc_ast::ast::Lifetime

pub struct Lifetime {
    pub id: NodeId,
    pub ident: Ident,
}

A “Lifetime” is an annotation of the scope in which variable can be used, e.g. 'a in &'a i32.

Fields

id: NodeId

ident: Ident

Trait Implementations

impl Clone for Lifetime

fn clone(&self) -> Lifetime

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lifetime

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for Lifetime

fn decode(__decoder: &mut __D) -> Self

impl Display for Lifetime

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

Formats the value using the given formatter.

impl<__E: SpanEncoder> Encodable<__E> for Lifetime

fn encode(&self, __encoder: &mut __E)

impl Hash for Lifetime

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Lifetime

fn eq(&self, other: &Lifetime) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Lifetime

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.
