Trait Implementations

impl Clone for Bits

fn clone(&self) -> Bits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl GroupSize for Bits

fn validate(&self) -> Result<Self, &'static str>

fn hash_to_group(&self, hash: u32) -> u8

Returns hash modulo self.

fn in_group_index(&self, hash: u64, group_seed: u16) -> u8

Returns index in the group with given seed group_seed using hasher which must be modified earlier by group_nr function.

fn bit_index_for_seed(&self, hash: u64, group_seed: u16, group: usize) -> usize

Returns bit index inside the group with number group and seed group_seed, assigned to the key hashed by the hasher.

fn level_size_groups_segments( &self, desired_total_size: usize, ) -> (usize, usize)

Returns number of groups and 64-bit segments for given desired_total_size.

fn copy_group_if_better<CB>( &self, dst: &mut [u64], src: &[u64], group_index: usize, callback: CB, )

where CB: FnOnce(),

Returns number of ones in the group. If group with given index has more ones in dst than in src, then copy it from src to dst and call callback.

fn write_size_bytes(&self) -> usize

Returns number of bytes that self.write writes to the output.

fn write(&self, output: &mut dyn Write) -> Result<()>

Writes self to output.

fn read(input: &mut dyn Read) -> Result<Self>

Reads Self from input.

impl Into<u8> for Bits

fn into(self) -> u8

Converts this type into the (usually inferred) input type.

impl Mul<usize> for Bits

type Output = usize

The resulting type after applying the * operator.

fn mul(self, rhs: usize) -> Self::Output

Performs the * operation.

impl SeedSize for Bits

type VecElement = u64

fn new_zeroed_seed_vec(&self, number_of_seeds: usize) -> Box<[Self::VecElement]>

fn new_seed_vec( &self, seed: u16, number_of_seeds: usize, ) -> Box<[Self::VecElement]>

unsafe fn get_seed(&self, vec: &[Self::VecElement], index: usize) -> u16

Gets seed with given index from vec. Does not check whether the index is within bounds.

unsafe fn set_seed(&self, vec: &mut [Self::VecElement], index: usize, seed: u16)

Writes self to output.

fn read(input: &mut dyn Read) -> Result<Self>

Reads Self from input.

impl TryFrom<u8> for Bits

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
