See the repository root README for API documentation and examples.

#
NormalizationForm

source
pub(all) enum NormalizationForm {
  NFD
  NFC
  NFKD
  NFKC
} derive(Eq)

Normalization form enumeration

#
is_normalized

source
fn is_normalized(s : String, form : NormalizationForm) -> Bool

Check if a string is in the specified normalization form

#
nfc

source
fn nfc(s : String) -> String

Normalize a string to NFC (Canonical Decomposition + Composition)

Characters are first decomposed canonically, reordered, then recomposed using canonical composition rules. This is the most commonly used normalization form.

#
nfd

source
fn nfd(s : String) -> String

Normalize a string to NFD (Canonical Decomposition)

Characters are decomposed to their canonical equivalents and combining marks are reordered by Canonical Combining Class.

#
nfkc

source
fn nfkc(s : String) -> String

Normalize a string to NFKC (Compatibility Decomposition + Composition)

Characters are decomposed to compatibility equivalents, reordered, then recomposed. Often used for identifier comparison.

#
nfkd

source
fn nfkd(s : String) -> String

Normalize a string to NFKD (Compatibility Decomposition)

Characters are decomposed to their compatibility equivalents (including formatting variants like superscripts, fractions, etc.) and combining marks are reordered.

#
normalize

source
fn normalize(s : String, form : NormalizationForm) -> String

Normalize a string to the specified form
