Struct CanonicalCombiningClassMapBorrowed

pub struct CanonicalCombiningClassMapBorrowed<'a> { /* private fields */ }

Borrowed version of lookup of the Canonical_Combining_Class Unicode property.

Example

use icu::properties::props::CanonicalCombiningClass;
use icu::normalizer::properties::CanonicalCombiningClassMapBorrowed;

let map = CanonicalCombiningClassMapBorrowed::new();
assert_eq!(map.get('a'), CanonicalCombiningClass::NotReordered); // U+0061: LATIN SMALL LETTER A
assert_eq!(map.get32(0x0301), CanonicalCombiningClass::Above); // U+0301: COMBINING ACUTE ACCENT

Implementations

impl CanonicalCombiningClassMapBorrowed<'static>

pub const fn static_to_owned(self) -> CanonicalCombiningClassMap

Cheaply converts a [CanonicalCombiningClassMapBorrowed<'static>] into a CanonicalCombiningClassMap.

Note: Due to branching and indirection, using CanonicalCombiningClassMap might inhibit some compile-time optimizations that are possible with CanonicalCombiningClassMapBorrowed.

pub const fn new() -> CanonicalCombiningClassMapBorrowed<'static>

Construct from compiled data.

✨ Enabled with the compiled_data Cargo feature.

📚 Help choosing a constructor

impl CanonicalCombiningClassMapBorrowed<'_>

pub fn get_u8(&self, c: char) -> u8

Look up the canonical combining class for a scalar value.

The return value is a u8 representing the canonical combining class, you may enable the "icu_properties" feature if you would like to use a typed CanonicalCombiningClass.

pub fn get32_u8(&self, c: u32) -> u8

Look up the canonical combining class for a scalar value represented as u32. If the argument is outside the scalar value range, Not_Reordered is returned.

The return value is a u8 representing the canonical combining class, you may enable the "icu_properties" feature if you would like to use a typed CanonicalCombiningClass.

Trait Implementations

impl<'a> Debug for CanonicalCombiningClassMapBorrowed<'a>

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

Formats the value using the given formatter.

impl Default for CanonicalCombiningClassMapBorrowed<'static>

fn default() -> CanonicalCombiningClassMapBorrowed<'static>

Returns the “default value” for a type.
