Trait UnicodeNormalization 

pub trait UnicodeNormalization {
    // Required methods
    fn nfc(&self) -> Cow<'_, str>;
    fn nfd(&self) -> Cow<'_, str>;
    fn nfkc(&self) -> Cow<'_, str>;
    fn nfkd(&self) -> Cow<'_, str>;
    fn is_nfc(&self) -> bool;
    fn is_nfd(&self) -> bool;
    fn is_nfkc(&self) -> bool;
    fn is_nfkd(&self) -> bool;
}

Convenience trait for normalizing &str slices.

All methods return Cow<'_, str>, which is Cow::Borrowed when the input is already in the target normalization form (zero allocation).

Required Methods

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

Normalize to NFC (Canonical Decomposition, followed by Canonical Composition).

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

Normalize to NFD (Canonical Decomposition).

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

Normalize to NFKC (Compatibility Decomposition, followed by Canonical Composition).

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

Normalize to NFKD (Compatibility Decomposition).

fn is_nfc(&self) -> bool

Check whether the string is already in NFC.

fn is_nfd(&self) -> bool

Check whether the string is already in NFD.

fn is_nfkc(&self) -> bool

Check whether the string is already in NFKC.

fn is_nfkd(&self) -> bool

Check whether the string is already in NFKD.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
