Struct UnicodeChar 

pub struct UnicodeChar {
    pub ch: char,
    pub code_point: u32,
    pub utf8_width: usize,
    pub utf16_width: usize,
    pub is_ascii: bool,
    pub is_combining: bool,
    pub is_surrogate: bool,
}

A Unicode scalar value bundled with precomputed metadata.

Fields

ch: char

The underlying Rust character.

code_point: u32

Unicode code point.

utf8_width: usize

UTF-8 encoded length (1-4 bytes).

utf16_width: usize

UTF-16 code unit count (1 or 2).

is_ascii: bool

True when ASCII.

is_combining: bool

True when a combining character (heuristic).

is_surrogate: bool

True when in surrogate range (never valid in Rust char).

Implementations

impl UnicodeChar

pub fn new(c: char) -> Self

Construct from a Rust char.

pub fn to_expr(&self) -> Expr

Build a kernel expression for this character.

pub fn block_name(&self) -> &'static str

Return simplified Unicode block name.

pub fn is_caseless(&self) -> bool

True when no case distinction.

Trait Implementations

impl Clone for UnicodeChar

fn clone(&self) -> UnicodeChar

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnicodeChar

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UnicodeChar

fn eq(&self, other: &UnicodeChar) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
