Trait Implementations

impl Clone for Precision4

fn clone(&self) -> Precision4

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Precision4

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

Formats the value using the given formatter.

impl Default for Precision4

fn default() -> Precision4

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Precision4

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Precision4

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 PartialEq<Precision4> for Precision4

fn eq(&self, other: &Precision4) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Precision for Precision4

type NumberOfZeros = u8

The data type to use for the number of zeros registers counter. This should be the smallest possinle data type that allows us to count all the registers without overflowing. We can tollerate a one-off error when counting the number of zeros, as it will be corrected when computing the cardinality as it is known before hand whether this can happen at all.

const EXPONENT: usize = 4usize

The exponent of the number of registers, meaning the number of registers that will be used is 2^EXPONENT.

const MAXIMAL: usize = 255usize

The maximal number that can be represented with the selected NumberOfZeros.

type SmallCorrrections = [f32; 16]

Type for small corrections:

const SMALL_CORRECTIONS: [f32; 16] = _

The precomputed small corrections used in the HyperLogLog algorithm for better performance.

const NUMBER_OF_REGISTERS: usize = _

The number of registers that will be used.

impl Serialize for Precision4

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl WordType<1> for Precision4

type Words = [u32; 1]

The type to use for the associated vector of words. The type of Words is always an array of u32, as this is the smallest type that can be used to store the number of registers.

impl WordType<2> for Precision4

type Words = [u32; 1]

The type to use for the associated vector of words. The type of Words is always an array of u32, as this is the smallest type that can be used to store the number of registers.

impl WordType<3> for Precision4

type Words = [u32; 2]

The type to use for the associated vector of words. The type of Words is always an array of u32, as this is the smallest type that can be used to store the number of registers.

impl WordType<4> for Precision4

type Words = [u32; 2]

The type to use for the associated vector of words. The type of Words is always an array of u32, as this is the smallest type that can be used to store the number of registers.

impl WordType<5> for Precision4

type Words = [u32; 3]

The type to use for the associated vector of words. The type of Words is always an array of u32, as this is the smallest type that can be used to store the number of registers.

impl WordType<6> for Precision4

type Words = [u32; 4]

The type to use for the associated vector of words. The type of Words is always an array of u32, as this is the smallest type that can be used to store the number of registers.
