Another Grid Library Except Terrible
This is a successor to my old crate cogs_gamedev’s grids module.
It adds opinionated integer-based coordinates and directions, along with some other useful things:
- Iterators over areas, edges of areas, and lines
Grid<T>, which is like aHashMap<Coord, T>but faster
Also supports serde, under the default feature serde.
Structs
- Represents a set of flags of some type
T.Tmust have the#[bitflags]attribute applied. - Unsigned-int coordinates
- Signed-int coordinates
- Like a
HashMap<Coord, T>but faster. Each grid point might store something. - Owning iterator over the filled slots in a
Grid. - Borrowing iterator over the filled slots in a
Grid. - Mutably borrowing iterator over the filled slots in a
Grid. - Iterates over coordinates on a line using Bresenham’s algorithm.
Enums
- Four-way directions.
- Eight-way directions.
- Nine-way directions: 8 compass points plus center.
- Where to stop the iteration of the line.
- 2-way rotations: clockwise or counterclockwise. These don’t indicate any specific angle by themselves, only in relation to something.
Traits
- A trait automatically implemented by
#[bitflags]to make the enum a valid type parameter forBitFlags<T>.
