Struct Glyph 

pub struct Glyph {
    pub ch: char,
    pub style: Style,
    pub src: usize,
    pub stop: bool,
}

One rendered character plus the source byte offset it originates from. Synthetic glyphs (a list bullet, a quote gutter) point at their block’s start, so clicking one lands the caret at the start of that block.

Fields

ch: char

style: Style

src: usize

stop: bool

Whether the caret may rest on this glyph. Decoration — a table border or a cell’s alignment padding — is visible but isn’t text, so the caret steps over it instead of into it. It also can’t be a stop even in principle: a run of decoration shares one src, and a caret can only move by changing offset, so resting on it would pin horizontal motion. A click still maps through src, which is why decoration points at the text it decorates.

Real text is a stop once per grapheme cluster, on the glyph that opens it: the continuation glyphs of an emoji or an accented letter are drawn, but standing between them is standing inside a character.
