Struct Script 

pub struct Script { /* private fields */ }

An ISO 15924 script identifier (four ASCII letters).

This type stores the canonical Titlecase form (e.g. Latn, Cyrl).

Implementations

impl Script

pub const UNKNOWN: Script

The “unknown” script (Zzzz).

pub const COMMON: Script

The “common” script (Zyyy).

pub const INHERITED: Script

The “inherited” script (Zinh).

pub const fn from_bytes(raw: [u8; 4]) -> Script

Creates a Script from raw ISO 15924 bytes.

The input must be four ASCII bytes in canonical form. This function does not validate.

The ASCII bytes can be provided as a byte array literal:

const LATIN: Script = Script::from_bytes(*b"Latn");

pub const fn from_str_unchecked(s: &str) -> Script

👎Deprecated since 0.1.1:

You should use from_bytes(*b"....") instead.

Creates a Script from a 4-byte string literal.

This was intended for const construction and does not validate the input. This method has been deprecated in favour of Self::from_bytes.

pub const fn to_bytes(self) -> [u8; 4]

Returns the raw ISO 15924 bytes.

pub fn as_str(&self) -> &str

Returns the canonical string form (e.g. Latn).

pub fn parse(s: &str) -> Result<Script, ParseScriptError>

Parses an ISO 15924 script identifier.

Parsing is case-insensitive; output is normalized to Titlecase (e.g. LATN → Latn).

pub const fn is_cursive(self) -> bool

Whether this is a cursive script according to CSS Text 3 Appendix D.

As per that specification, “these scripts do not admit gaps between their letters for either justification or letter-spacing.”

See also CSS Text 3 § 6.4.4 on cursive justification.
