pub fn normalize_iter<I: Iterator<Item = char>>( &self, iter: I, ) -> Decomposition<'_, I>

Wraps a delegate iterator into a decomposing iterator adapter by using the data already held by this normalizer.

pub fn normalize(&self, text: &str) -> String

Normalize a string slice into a String.

pub fn is_normalized(&self, text: &str) -> bool

Check whether a string slice is normalized.

pub fn normalize_utf16(&self, text: &[u16]) -> Vec<u16>

Normalize a slice of potentially-invalid UTF-16 into a Vec.

Unpaired surrogates are mapped to the REPLACEMENT CHARACTER before normalizing.

pub fn is_normalized_utf16(&self, text: &[u16]) -> bool

Checks whether a slice of potentially-invalid UTF-16 is normalized.

Unpaired surrogates are treated as the REPLACEMENT CHARACTER.

pub fn normalize_utf8(&self, text: &[u8]) -> String

Normalize a slice of potentially-invalid UTF-8 into a String.

Ill-formed byte sequences are mapped to the REPLACEMENT CHARACTER according to the WHATWG Encoding Standard.

pub fn is_normalized_utf8(&self, text: &[u8]) -> bool

Check if a slice of potentially-invalid UTF-8 is normalized.

Ill-formed byte sequences are mapped to the REPLACEMENT CHARACTER according to the WHATWG Encoding Standard before checking.

pub fn normalize_to<W: Write + ?Sized>( &self, text: &str, sink: &mut W, ) -> Result

Normalize a string slice into a Write sink.

pub fn normalize_utf8_to<W: Write + ?Sized>( &self, text: &[u8], sink: &mut W, ) -> Result

Normalize a slice of potentially-invalid UTF-8 into a Write sink.

Ill-formed byte sequences are mapped to the REPLACEMENT CHARACTER according to the WHATWG Encoding Standard.

pub fn normalize_utf16_to<W: Write16 + ?Sized>( &self, text: &[u16], sink: &mut W, ) -> Result

Normalize a slice of potentially-invalid UTF-16 into a Write16 sink.

Unpaired surrogates are mapped to the REPLACEMENT CHARACTER before normalizing.
