You can use this package in your project by adding the following to your Cargo.toml:

[dependencies]
unicode-normalization = "0.1.20"

Modules

• char
  Methods for composing and decomposing characters.

Structs

• Decompositions
  External iterator for a string decomposition’s characters.
• Recompositions
  External iterator for a string recomposition’s characters.
• Replacements
  External iterator for replacements for a string’s characters.
• StreamSafe
  UAX15-D4: This iterator keeps track of how many non-starters there have been since the last starter in NFKD and will emit a Combining Grapheme Joiner (U+034F) if the count exceeds 30.

Enums

• IsNormalized
  QuickCheck quickly determines if a string is normalized, it can return Maybe

Constants

• UNICODE_VERSION

Traits

• UnicodeNormalization
  Methods for iterating over strings while applying Unicode normalizations as described in Unicode Standard Annex #15.

Functions

• is_nfc
  Authoritatively check if a string is in NFC.
• is_nfc_quick
  Quickly check if a string is in NFC, potentially returning IsNormalized::Maybe if further checks are necessary. In this case a check like s.chars().nfc().eq(s.chars()) should suffice.
• is_nfc_stream_safe
  Authoritatively check if a string is Stream-Safe NFC.
• is_nfc_stream_safe_quick
  Quickly check if a string is Stream-Safe NFC.
• is_nfd
  Authoritatively check if a string is in NFD.
• is_nfd_quick
  Quickly check if a string is in NFD.
• is_nfd_stream_safe
  Authoritatively check if a string is Stream-Safe NFD.
• is_nfd_stream_safe_quick
  Quickly check if a string is Stream-Safe NFD.
• is_nfkc
  Authoritatively check if a string is in NFKC.
• is_nfkc_quick
  Quickly check if a string is in NFKC.
• is_nfkd
  Authoritatively check if a string is in NFKD.
• is_nfkd_quick
  Quickly check if a string is in NFKD.
