Trait Implementations

impl Clone for Precision14

fn clone(&self) -> Precision14

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Precision14

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

Formats the value using the given formatter.

impl Default for Precision14

fn default() -> Precision14

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Precision14

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

Deserialize this value from the given Serde deserializer.

impl Hash for Precision14

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<Precision14> for Precision14

fn eq(&self, other: &Precision14) -> 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 Precision14

type NumberOfZeros = u16

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 = 14usize

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

const MAXIMAL: usize = 65_535usize

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

type SmallCorrrections = [f32; 16384]

Type for small corrections:

const SMALL_CORRECTIONS: [f32; 16384] = _

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 Precision14

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 Precision14

type Words = [u32; 512]

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 Precision14

type Words = [u32; 1024]

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 Precision14

type Words = [u32; 1639]

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 Precision14

type Words = [u32; 2048]

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 Precision14

type Words = [u32; 2731]

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 Precision14

type Words = [u32; 3277]

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.
