Struct CellSelection 

pub struct CellSelection {
    pub node: Key,
    pub anchor: CellEnd,
    pub focus: CellEnd,
    pub block: bool,
}

A selection inside one cells grid.

Fields

node: Key

The grid it lives in.

anchor: CellEnd

focus: CellEnd

block: bool

Rectangular rather than linewise: the column range is the same on every line, which is how a terminal selects a column of output. Held by a modifier while dragging, the way every terminal does it.

Implementations

impl CellSelection

pub fn new(node: Key, anchor: CellEnd, focus: CellEnd) -> Self

pub fn block(self, on: bool) -> Self

pub fn is_empty(&self) -> bool

pub fn to_value(self, handles: Handles) -> Value

The selection as data — {node, anchor: {line, col}, focus: {line, col}, block}, the ends as the drag made them (directed, like RangeEnd::to_value’s) and the lines absolute: the shape a binding’s cell_selection reads back, spelled once.

pub fn ordered(&self) -> (CellEnd, CellEnd)

The two ends in reading order.

pub fn cols_on(&self, line: u64, cols: usize) -> Option<(usize, usize)>

The columns selected on line, as a half-open range, or None when the line is outside the selection. Linewise by default — a line in the middle runs edge to edge, which cols gives — and a block selection is the same column range on every line it covers.
