Struct Rect 

pub struct Rect {
    x: usize,
    y: usize,
    w: Option<usize>,
    h: Option<usize>,
}

A rectangle of grid cells, selected by column and row ranges. Coordinates are 0-based from the top-left of the scope the rect is used in.

Built by giving both axes, in either order. See SpanBounds for the accepted range forms.

use steel_core::inventory::menu::Rect;

Rect::cols(3..6).rows(1);      // columns 3,4,5 of row 1
Rect::rows(1..=2).cols(..4);   // the same rect, axes given in the other order
Rect::cols(4..).rows(..);      // column 4 to the right edge, all rows
Rect::cell(6, 2);              // single cell, shorthand for cols(6).rows(2)

Unbounded ends resolve against the enclosing scope, so the same rect means “to the edge” inside a subgrid too.

Fields

x: usize

y: usize

w: Option<usize>

None runs to the scope’s right edge.

h: Option<usize>

None runs to the scope’s bottom edge.

Implementations

impl Rect

pub fn cols(cols: impl SpanBounds) -> ColSpan

Starts a rect from a column selection. Finish it with ColSpan::rows.

Panics

If the range is empty.

pub fn rows(rows: impl SpanBounds) -> RowSpan

Starts a rect from a row selection. Finish it with RowSpan::cols.

Panics

If the range is empty.

pub const fn cell(x: usize, y: usize) -> Self

A single cell at column x, row y.
