impl LineBreak

pub fn get_name_to_enum_mapper( provider: &impl DataProvider<LineBreakNameToValueV1Marker> + ?Sized ) -> Result<PropertyValueNameToEnumMapper<LineBreak>, PropertiesError>

Return a PropertyValueNameToEnumMapper, capable of looking up values from strings for the Line_Break enumerated property

Example

use icu::properties::LineBreak;

let lookup = LineBreak::get_name_to_enum_mapper(&icu_testdata::unstable())
                 .expect("The data should be valid");
let lookup = lookup.as_borrowed();
// short name for value
assert_eq!(lookup.get_strict("BK"), Some(LineBreak::MandatoryBreak));
assert_eq!(lookup.get_strict("AL"), Some(LineBreak::Alphabetic));
// long name for value
assert_eq!(lookup.get_strict("Mandatory_Break"), Some(LineBreak::MandatoryBreak));
assert_eq!(lookup.get_strict("Alphabetic"), Some(LineBreak::Alphabetic));
// name has incorrect casing and dash instead of underscore
assert_eq!(lookup.get_strict("mandatory-Break"), None);
// loose matching of name
assert_eq!(lookup.get_loose("mandatory-Break"), Some(LineBreak::MandatoryBreak));
// fake property
assert_eq!(lookup.get_strict("Stochastic_Break"), None);

pub fn get_enum_to_short_name_mapper( provider: &impl DataProvider<LineBreakValueToShortNameV1Marker> + ?Sized ) -> Result<PropertyEnumToValueNameLinearMapper<LineBreak>, PropertiesError>

Return a PropertyEnumToValueNameLinearMapper, capable of looking up short names for values of the Line_Break enumerated property

Example

use icu::properties::LineBreak;

let lookup = LineBreak::get_enum_to_short_name_mapper(&icu_testdata::unstable())
                 .expect("The data should be valid");
let lookup = lookup.as_borrowed();
assert_eq!(lookup.get(LineBreak::MandatoryBreak), Some("BK"));
assert_eq!(lookup.get(LineBreak::Alphabetic), Some("AL"));

pub fn get_enum_to_long_name_mapper( provider: &impl DataProvider<LineBreakValueToLongNameV1Marker> + ?Sized ) -> Result<PropertyEnumToValueNameLinearMapper<LineBreak>, PropertiesError>

Return a PropertyEnumToValueNameLinearMapper, capable of looking up long names for values of the Line_Break enumerated property

Example

use icu::properties::LineBreak;

let lookup = LineBreak::get_enum_to_long_name_mapper(&icu_testdata::unstable())
                 .expect("The data should be valid");
let lookup = lookup.as_borrowed();
assert_eq!(lookup.get(LineBreak::MandatoryBreak), Some("Mandatory_Break"));
assert_eq!(lookup.get(LineBreak::Alphabetic), Some("Alphabetic"));

Trait Implementations

impl AsULE for LineBreak

type ULE = LineBreakULE

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

fn from_unaligned(unaligned: Self::ULE) -> Self

Converts from Self::ULE to Self.

impl Bake for LineBreak

fn bake(&self, env: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl Clone for LineBreak

fn clone(&self) -> LineBreak

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LineBreak

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LineBreak

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

Deserialize this value from the given Serde deserializer.

impl Ord for LineBreak

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<LineBreak> for LineBreak

fn eq(&self, other: &LineBreak) -> 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 PartialOrd<LineBreak> for LineBreak

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

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

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

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

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

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

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

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

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

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

impl Serialize for LineBreak

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

Serialize this value into the given Serde serializer.

impl TrieValue for LineBreak

type TryFromU32Error = TryFromIntError

Last-resort fallback value to return if we cannot read data from the trie.

fn try_from_u32(i: u32) -> Result<Self, Self::TryFromU32Error>

A parsing function that is primarily motivated by deserialization contexts. When the serialization type width is smaller than 32 bits, then it is expected that the call site will widen the value to a u32 first.

fn to_u32(self) -> u32

A method for converting back to a u32 that can roundtrip through Self::try_from_u32(). The default implementation of this trait method panics in debug mode and returns 0 in release mode.

impl<'a> ZeroMapKV<'a> for LineBreak

type Container = ZeroVec<'a, LineBreak>

The container that can be used with this type: ZeroVec or VarZeroVec.

type Slice = ZeroSlice<LineBreak>

type GetType = LineBreakULE

The type produced by Container::get()

type OwnedType = LineBreak

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()
