Struct Gutter 

pub struct Gutter {
    pub width: u16,
    pub style: Style,
    pub line_offset: usize,
}

Configuration for the line-number gutter rendered to the left of the text area. width is the total cell count reserved (including any trailing spacer); the renderer right-aligns the 1-based row number into the leftmost width - 1 cells.

line_offset is added to the displayed line number, so a host rendering a windowed view of a larger document (e.g. picker preview of a 7000-line buffer) can show the original line numbers instead of starting at 1.

Fields

width: u16

style: Style

line_offset: usize
