Struct CaseMapper

pub struct CaseMapper { /* private fields */ }

A struct with the ability to convert characters and strings to uppercase or lowercase, or fold them to a normalized form for case-insensitive comparison.

Most methods for this type live on CaseMapperBorrowed, which you can obtain via CaseMapper::new() or CaseMapper::as_borrowed().

Examples

use icu::casemap::CaseMapper;
use icu::locale::langid;

let cm = CaseMapper::new();

assert_eq!(
    cm.uppercase_to_string("hello world", &langid!("und")),
    "HELLO WORLD"
);
assert_eq!(
    cm.lowercase_to_string("Γειά σου Κόσμε", &langid!("und")),
    "γειά σου κόσμε"
);

Implementations

impl CaseMapper

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

Creates a CaseMapperBorrowed using compiled data.

✨ Enabled with the compiled_data Cargo feature.

Examples

use icu::casemap::CaseMapper;
use icu::locale::langid;

let cm = CaseMapper::new();

assert_eq!(
    cm.uppercase_to_string("hello world", &langid!("und")),
    "HELLO WORLD"
);

pub fn as_borrowed(&self) -> CaseMapperBorrowed<'_>

Constructs a borrowed version of this type for more efficient querying.

pub fn try_new_with_buffer_provider( provider: &(impl BufferProvider + ?Sized), ) -> Result<Self, DataError>

A version of [Self :: new] that uses custom data provided by a BufferProvider.

✨ Enabled with the serde feature.

pub fn try_new_unstable<P>(provider: &P) -> Result<CaseMapper, DataError>

where P: DataProvider<CaseMapV1> + ?Sized,

A version of Self::new that uses custom data provided by a DataProvider.
