grid_shapes was born from the need of a dedicated shapes library for drawing shapes on a grid. (eg. drawing a room in a roguelike dungeon)
There are many shapes libraries but most use floating point math and I needed something simple. Each shape is defined inclusively for example a rectangle with min and max coordinates of (0,0) and (4,4) would return a size of [5,5] as both (0,0) and (4,4) are considered legitimate positions in the rectangle.
Currently the included shapes are: Rectangle Line Circle
This list will grow over time, and the functions will become more standardized across each of them.
Each shape is a generic struct using traits to implement the Coord and Size. And the crate "coord2d" can provide a default implementation with the "coord2d" feature.
Accessing the coords which make up each shape is preferably done through iterators. A helper function (shape).for_each(|coord| {}) has been provided.
I am open to suggestions and pr's.
