bitmac

This library provides implementation of bitmap with custom bit accessing and resizing strategy.

toml [dependencies] bitmac = "0.1"

Resizing strategy

This library provides several resizing strategy.

MinimalRequiredStrategy - resize to minimum required bytes
FixedStrategy - advance size by fixed steps
StaticStrategy - never increases the size, returns an error if an increase is required, useful for const containers ([u8; N])

You can implement your own ResizingStrategy.

BitAccess

The bytes in a bitmap can be stored in LSB or MSB order. In LSB order, the 0th bit of the bitmap is the least significant bit, i.e. 0b0000_0001 it means that bitmap.get(0) == true and on the other hand for the MSB (most significant bit) order, this means that bitmap.get(7) == true.

Example

```rust use bitmac::{Bitmap, MinimumRequiredStrategy, LSB};

fn main() { let mut bitmap = Bitmap::, MinimumRequiredStrategy, LSB>::default();

assert_eq!(bitmap.as_bytes().len(), 0);

bitmap.set(0, true);
bitmap.set(7, true);
assert_eq!(bitmap.as_bytes().len(), 1);

bitmap.set(15, true);
assert_eq!(bitmap.as_bytes().len(), 2);

assert!(bitmap.get(0));
assert!(bitmap.get(7));
assert!(bitmap.get(15));

assert!(!bitmap.get(1));
assert!(!bitmap.get(8));
assert!(!bitmap.get(300));

assert_eq!(bitmap.as_bytes().len(), 2);

} ```
