Struct icu_locid::extensions::unicode::Value

pub struct Value(_);

A value used in a list of Keywords.

The value has to be a sequence of one or more alphanumerical strings separated by -. Each part of the sequence has to be no shorter than three characters and no longer than 8.

Examples

use icu::locid::extensions::unicode::Value;

let value1: Value = "gregory".parse()
    .expect("Failed to parse a Value.");
let value2: Value = "islamic-civil".parse()
    .expect("Failed to parse a Value.");

assert_eq!(&value1.to_string(), "gregory");
assert_eq!(&value2.to_string(), "islamic-civil");

Implementations

impl Value

pub fn from_bytes(input: &[u8]) -> Result<Self, ParserError>

A constructor which takes a utf8 slice, parses it and produces a well-formed Value.

Examples

use icu::locid::extensions::unicode::Value;

let value = Value::from_bytes(b"buddhist")
    .expect("Parsing failed.");

assert_eq!(&value.to_string(), "buddhist");

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Display for Value

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

Formats the value using the given formatter.

impl Eq for Value

impl FromStr for Value

type Err = ParserError

The associated error which can be returned from parsing.

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

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

impl Hash for Value

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Ord for Value

fn cmp(&self, other: &Value) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Value> for Value

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

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

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

This method tests for !=.

impl PartialOrd<Value> for Value

fn partial_cmp(&self, other: &Value) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

impl StructuralEq for Value

impl StructuralPartialEq for Value

impl Writeable for Value

fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result

Writes bytes to the given sink. Errors from the sink are bubbled up.

fn write_len(&self) -> LengthHint

Returns a hint for the number of bytes that will be written to the sink.

pub fn writeable_to_string(&self) -> String

Creates a new String with the data from this Writeable. Like ToString, but smaller and faster.
