Struct EnumVariantContiguousIndex 

pub(crate) struct EnumVariantContiguousIndex(usize);

An index type for enum variants. This ranges from 0 to variants.len(), whereas EnumVariantId can take arbitrary large values (and hence mustn’t be used with IndexVec/BitSet).

Tuple Fields

0: usize

Implementations

impl EnumVariantContiguousIndex

fn from_enum_variant_id( db: &dyn HirDatabase, target_evid: EnumVariantId, ) -> Self

fn to_enum_variant_id(self, db: &dyn HirDatabase, eid: EnumId) -> EnumVariantId

Trait Implementations

impl Clone for EnumVariantContiguousIndex

fn clone(&self) -> EnumVariantContiguousIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnumVariantContiguousIndex

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

Formats the value using the given formatter.

impl Hash for EnumVariantContiguousIndex

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 Idx for EnumVariantContiguousIndex

fn new(idx: usize) -> Self

fn index(self) -> usize

fn increment_by(&mut self, amount: usize)

fn plus(self, amount: usize) -> Self

impl PartialEq for EnumVariantContiguousIndex

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