[−][src]Trait rqrr::Grid

pub trait Grid {
    fn size(&self) -> usize;

    fn bit(&self, y: usize, x: usize) -> bool;
}

A grid that contains exactly one QR code square.

The common trait for everything that can be decoded as a QR code. Given a normal image, we first need to find the QR grids in it. See capstones_from_image, find_groupings and SkewedGridLocation.

This trait can be implemented when some object is known to be exactly the bit-pattern of a QR code.

Required methods

fn size(&self) -> usize

Return the size of the grid.

Since QR codes are always squares, the grid is assumed to be size * size.

fn bit(&self, y: usize, x: usize) -> bool

Return the value of the bit at the given location.

true means 'black', false means 'white'
