Struct rustc_index::bit_set::FiniteBitSet

pub struct FiniteBitSet<T: FiniteBitSetTy>(pub T);

A fixed-sized bitset type represented by an integer type. Indices outwith than the range representable by T are considered set.

Tuple Fields

0: T

Implementations

impl<T: FiniteBitSetTy> FiniteBitSet<T>

pub fn new_empty() -> Self

Creates a new, empty bitset.

pub fn set(&mut self, index: u32)

Sets the indexth bit.

pub fn clear(&mut self, index: u32)

Unsets the indexth bit.

pub fn set_range(&mut self, range: Range<u32>)

Sets the ith to jth bits.

pub fn is_empty(&self) -> bool

Is the set empty?

pub fn within_domain(&self, index: u32) -> bool

Returns the domain size of the bitset.

pub fn contains(&self, index: u32) -> Option<bool>

Returns if the indexth bit is set.

Trait Implementations

impl<T: Clone + FiniteBitSetTy> Clone for FiniteBitSet<T>

fn clone(&self) -> FiniteBitSet<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FiniteBitSet<u32>

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

Formats the value using the given formatter.

impl<T, __D: Decoder> Decodable<__D> for FiniteBitSet<T>

where T: Decodable<__D> + FiniteBitSetTy,

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

impl<T: FiniteBitSetTy> Default for FiniteBitSet<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T, __E: Encoder> Encodable<__E> for FiniteBitSet<T>

where T: Encodable<__E> + FiniteBitSetTy,

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

impl<T: PartialEq + FiniteBitSetTy> PartialEq for FiniteBitSet<T>

fn eq(&self, other: &FiniteBitSet<T>) -> 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<T: Copy + FiniteBitSetTy> Copy for FiniteBitSet<T>

impl<T: Eq + FiniteBitSetTy> Eq for FiniteBitSet<T>

impl<T: FiniteBitSetTy> StructuralPartialEq for FiniteBitSet<T>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
