The precision of the BJKST data structure, in bits.

A Bjkst with precision p can store up to 2^p elements before shrinking. The internal array will be at most twice as large.

Default precision is 16 bits, that is, 65,536 elements.

Implementations

impl Precision

pub const MIN: Self = Self::P1

The smallest precision value.

pub const MAX: Self = Self::P24

The largest precision value.

pub const fn new(value: u8) -> Option<Precision>

Creates a new Precision if the given value is valid.

pub const fn get(&self) -> u8

Returns the precision value as a primitive type.

pub const fn variants() -> &'static [Precision]

Returns the precision variants.

pub fn in_range(&self, value: u8) -> bool

Checks whether the given value is in the range of available precisions.

pub fn from_str_radix(src: &str, radix: u32) -> Result<Self, ParseError>

Converts a string slice in a given base to a precision.

The string is expected to be an optional + sign followed by digits. Leading and trailing whitespace represent an error. Digits are a subset of these characters, depending on radix:

• 0-9
• a-z
• A-Z

Panics

Panics if radix is not in the range from 2 to 36.

Examples

use uniq_ch::Precision;

assert_eq!(Precision::from_str_radix("10", 10), Ok(Precision::P10));

Trait Implementations

fn clone(&self) -> Precision

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Precision

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

Formats the value using the given formatter.

impl Default for Precision

fn default() -> Precision

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Precision

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Precision

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

Formats the value using the given formatter.

impl From<Precision> for u8

fn from(precision: Precision) -> Self

Converts to this type from the input type.

impl FromStr for Precision

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(src: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Precision

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)
