Struct PatternEnumVariant

pub struct PatternEnumVariant {
    pub variant: ConcreteVariant,
    pub inner_pattern: Option<PatternId>,
    pub ty: TypeId,
    pub stable_ptr: PatternPtr,
}

A pattern that destructures a specific variant of an enum to its inner value.

Fields

variant: ConcreteVariant

inner_pattern: Option<PatternId>

ty: TypeId

stable_ptr: PatternPtr

Trait Implementations

impl Clone for PatternEnumVariant

fn clone(&self) -> PatternEnumVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PatternEnumVariant

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

Formats the value using the given formatter.

impl<'a, T: ?Sized + Upcast<ExprFormatter<'a>>> DebugWithDb<T> for PatternEnumVariant

fn fmt(&self, f: &mut Formatter<'_>, other_db: &T) -> Result

fn debug<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

fn into_debug<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

impl Hash for PatternEnumVariant

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 PatternEnumVariant

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