Struct LineDelta 

pub struct LineDelta {
    pub start: u32,
    pub old_lines: u32,
    pub new_lines: u32,
}

How the line count changed under one edit — the scope signal a buffer mutation reports up to the refresh tree. start is the first line the edit touched; the counts let a consumer tell an in-place edit (old == new, damage is local) from one that shifted every line below (old != new, damage runs to the end of the document).

Fields

start: u32

old_lines: u32

new_lines: u32

Implementations

impl LineDelta

pub fn shifted_below(self) -> bool

Did this edit change the number of lines? If so, every line below start shifted and the damage runs to the end of the document.
