Struct rustc_ast::ast::BindingMode

pub struct BindingMode(pub ByRef, pub Mutability);

The mode of a binding (mut, ref mut, etc). Used for both the explicit binding annotations given in the HIR for a binding and the final binding mode that we infer after type inference/match ergonomics. .0 is the by-reference mode (ref, ref mut, or by value), .1 is the mutability of the binding.

Tuple Fields

0: ByRef

1: Mutability

Implementations

impl BindingMode

pub const NONE: Self = _

pub const REF: Self = _

pub const REF_MUT: Self = _

pub const MUT_REF: Self = _

pub const MUT_REF_MUT: Self = _

pub fn prefix_str(self) -> &'static str

Trait Implementations

impl Clone for BindingMode

fn clone(&self) -> BindingMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BindingMode

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

Formats the value using the given formatter.

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

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

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

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

impl<__CTX> HashStable<__CTX> for BindingMode

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq for BindingMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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.
