Just what the world needed - yet another bit field struct.
This is a small and simple implementation. It only has the basic functionality of a bit field: * Set arbitrary bit (if you set the millionth bit the list will use at least 125KB of heap space) * Get bit value * An iterator over the set bit indices. O(size of container) * The container never shrinks.
yabf::Yabf is a std::vec::Vec based bit field
rust
let mut a = Yabf::default();
let mut b = Yabf::with_capacity(12345);
// bits are false by default
assert_eq!(a.bit(45), false);
a.set_bit(12345, true);
assert_eq!(a.bit(12345), true);
b.set_bit(345, true);
assert_eq!(b.bit(345), true);
yabf::SmallYabf is a smallvec::SmallVec based bit field. The struct will be entirely
stack allocated if it contains less than 129 bits.
rust
let mut a = SmallYabf::default();
let mut b = SmallYabf::with_capacity(12345);
a.set_bit(45, false);
b.set_bit(12345, true);
assert_eq!(a.bit(45), false);
assert_eq!(b.bit(12345), true);
assert_eq!(a.bit(12345), false);
yabf::SmallYabf is enabled by default, disable like this:
toml
yabf = {version="0.2",default-features=false}
yabf::SmallYabf is enabled by default
toml
yabf = {version="0.2"}
