Enum rustc_hir::MatchSource

pub enum MatchSource {
    Normal,
    ForLoopDesugar,
    TryDesugar,
    AwaitDesugar,
}

Hints at the original code for a match _ { .. }.

Variants

Normal

A match _ { .. }.

ForLoopDesugar

A desugared for _ in _ { .. } loop.

TryDesugar

A desugared ? operator.

AwaitDesugar

A desugared <expr>.await.

Implementations

impl MatchSource

pub const fn name(self) -> &'static str

Trait Implementations

impl Clone for MatchSource

fn clone(&self) -> MatchSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MatchSource

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

Formats the value using the given formatter.

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

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

impl Hash for MatchSource

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<__CTX> HashStable<__CTX> for MatchSourcewhere
    __CTX: HashStableContext,

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

impl PartialEq<MatchSource> for MatchSource

fn eq(&self, other: &MatchSource) -> 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.
