Struct BitSet 

pub struct BitSet { /* private fields */ }

Bit set providing fast operations on large arrays of bits.

Implementations

impl BitSet

pub fn new(bit_capacity: u32) -> BitSet

(b3CreateBitSet)

pub fn destroy(&mut self)

Release the storage. (b3DestroyBitSet)

Rust would drop the storage automatically; this mirrors the C function so ported call sites read the same.

pub fn set_bit_count_and_clear(&mut self, bit_count: u32)

(b3SetBitCountAndClear)

pub fn grow(&mut self, block_count: u32)

(b3GrowBitSet)

pub fn in_place_union(&mut self, other: &BitSet)

In-place union: self |= other. (b3InPlaceUnion)

pub fn count_set_bits(&self) -> i32

Count the number of set bits. (b3CountSetBits, from table.c)

pub fn set_bit(&mut self, bit_index: u32)

Set a bit that must lie within the current block count. (b3SetBit)

pub fn set_bit_grow(&mut self, bit_index: u32)

Set a bit, growing the set if needed. (b3SetBitGrow)

pub fn clear_bit(&mut self, bit_index: u32)

Clear a bit. Out-of-range indices are ignored. (b3ClearBit)

pub fn get_bit(&self, bit_index: u32) -> bool

Get a bit. Out-of-range indices read as false. (b3GetBit)

pub fn bytes(&self) -> i32

Byte size of the allocated storage. (b3GetBitSetBytes)

pub fn block_count(&self) -> u32

Number of active 64-bit blocks (blockCount in C). Used together with BitSet::block to port the C word/CTZ set-bit iteration loops.

pub fn block(&self, block_index: u32) -> u64

The k-th active 64-bit block (bits[k] in C).

Trait Implementations

impl Clone for BitSet

fn clone(&self) -> BitSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BitSet

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

Formats the value using the given formatter.

impl Default for BitSet

fn default() -> BitSet

Returns the “default value” for a type.
