Struct icu::locale::extensions::transform::Value

pub struct Value(/* private fields */);

A value used in a list of Fields.

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::locale::extensions::transform::Value;

"hybrid".parse::<Value>().expect("Valid Value.");

"hybrid-foobar".parse::<Value>().expect("Valid Value.");

"no".parse::<Value>().expect_err("Invalid Value.");

Implementations

impl Value

pub fn try_from_str(s: &str) -> Result<Value, ParseError>

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

Examples

use icu::locale::extensions::transform::Value;

let value = Value::try_from_str("hybrid").expect("Parsing failed.");

pub fn try_from_utf8(code_units: &[u8]) -> Result<Value, ParseError>

See Self::try_from_str

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl Display for Value

This trait is implemented for compatibility with fmt!. To create a string, [Writeable::write_to_string] is usually more efficient.

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

Formats the value using the given formatter.

impl FromStr for Value

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Value, <Value as FromStr>::Err>

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

impl Hash for Value

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

where __H: Hasher,

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 Ord for Value

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Value

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Value

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Writeable for Value

fn write_to<W>(&self, sink: &mut W) -> Result<(), Error>

where W: Write + ?Sized,

Writes a string to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to_parts, and discards any Part annotations.

fn writeable_length_hint(&self) -> LengthHint

Returns a hint for the number of UTF-8 bytes that will be written to the sink.

fn write_to_string(&self) -> Cow<'_, str>

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

fn write_to_parts<S>(&self, sink: &mut S) -> Result<(), Error>

where S: PartsWrite + ?Sized,

Write bytes and Part annotations to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to, and doesn’t produce any Part annotations.
