Struct DecompRef 

pub struct DecompRef<'a> {
    pub zigen: &'a [char],
    pub strokes: &'a [Stroke],
    pub shape: Shape,
}

Borrowed character decomposition. Cheap to construct from &[char] / &[Stroke], suitable for both stack-only build pipelines and the runtime hot path.

Fields

zigen: &'a [char]

Ordered 字根 sequence (1..=N items). Encoder consumes positions [0, 1, 2, last].

strokes: &'a [Stroke]

Stroke sequence for 成字字根 / 末笔识别码 rules. May be longer than zigen; only the first/second/last positions are read.

shape: Shape

Whole-character shape — drives the 末笔识别码 lookup.

Implementations

impl<'a> DecompRef<'a>

pub fn first_stroke(&self) -> Option<Stroke>

First stroke, or None for an empty stroke list.

pub fn second_stroke(&self) -> Option<Stroke>

Second stroke (index 1), or None if fewer than 2 strokes.

pub fn last_stroke(&self) -> Option<Stroke>

Last stroke, or None for an empty stroke list. Used by the 识别码 rule for 2- and 3-字根 codes.
