Struct BodyHit 

pub struct BodyHit {
    pub zone: PaneHitZone,
    pub row_offset: u16,
    pub text_col: Option<u16>,
    pub origin: Option<RowOrigin>,
}

A screen cell resolved against the painted layout.

Still in display space: row_offset counts painted rows, which under soft wrap or a closed fold is not a source line, and text_col counts display columns, which inlays and conceals shift away from source positions. Turning those into a buffer position is the renderer’s next step, and it does it by inverting the same forward maps the caret is drawn with — see docs/dev/architecture/mouse.md.

Fields

zone: PaneHitZone

row_offset: u16

Rows below the top of the pane’s content area.

text_col: Option<u16>

Display columns right of the first text cell, or None when the cell is on the gutter.

origin: Option<RowOrigin>

Which logical line (and wrap segment) this row was painted from. None when the pane recorded no rows at all — a pane composed before this frame’s paint, or one whose content path does not go through the shared composer.

Implementations

impl BodyHit

pub fn logical_col(&self, body_width: u32) -> Option<u32>

The display column within the LOGICAL line, undoing soft wrap and horizontal scroll.

None on the gutter or on a row with no source line. The two terms are exclusive in practice — leftcol is forced to 0 under wrap — so adding both is correct rather than merely convenient.
