Module std::bit_vector

Struct BitVector​

public struct BitVector has copy, drop, store
Click to open
Fields
length: u64
bit_field: vector<bool>

Constants​

The provided index is out of bounds

const EINDEX: u64 = 131072;

An invalid length of bitvector was given

const ELENGTH: u64 = 131073;

const WORD_SIZE: u64 = 1;

The maximum allowed bitvector size

const MAX_SIZE: u64 = 1024;

Function new​

Function set​

Set the bit at bit_index in the bitvector regardless of its previous state.

public fun set(bitvector: &mut std::bit_vector::BitVector, bit_index: u64)

Function unset​

Unset the bit at bit_index in the bitvector regardless of its previous state.

public fun unset(bitvector: &mut std::bit_vector::BitVector, bit_index: u64)

Function shift_left​

Shift the bitvector left by amount. If amount is greater than the bitvector's length the bitvector will be zeroed out.

public fun shift_left(bitvector: &mut std::bit_vector::BitVector, amount: u64)

Function is_index_set​

Return the value of the bit at bit_index in the bitvector. true represents "1" and false represents a 0

public fun is_index_set(bitvector: &std::bit_vector::BitVector, bit_index: u64): bool

Function length​

Return the length (number of usable bits) of this bitvector

public fun length(bitvector: &std::bit_vector::BitVector): u64

Function longest_set_sequence_starting_at​

Returns the length of the longest sequence of set bits starting at (and including) start_index in the bitvector. If there is no such sequence, then 0 is returned.

public fun longest_set_sequence_starting_at(bitvector: &std::bit_vector::BitVector, start_index: u64): u64
