Struct KeyGrid 

Source 
struct KeyGrid<const ROW: usize, const COL: usize> {
    cells: [[KeyState; COL]; ROW],
}
Expand description

A 2D grid of [KeyState] values representing the current state of all keys.

Fields§

§cells: [[KeyState; COL]; ROW]

The key state for each position in the matrix.

Implementations§

Source§

impl<const ROW: usize, const COL: usize> KeyGrid<ROW, COL>

Source

const fn get_mut(&mut self, row: usize, col: usize) -> Option<&mut KeyState>

Returns a mutable reference to the [KeyState] at the given row and column, or [None] if either index is out of bounds.

Source

fn new() -> Self

Creates a new KeyGrid with all keys initialized to the released state.
