}Optimized implementation.
This implementation uses static arrays for constant-time lookup. It also uses a phantom type to enable static dispatch on demand.
Fields
val: &'static [u8]
Symbol to value association.
This array must have size 256 and defines val(s) as
Some(val[s]) if val[s] < 128 and None otherwise.
sym: &'static [u8]
Value to symbol association.
This array must have size 1 << b and defines sym(v) as
sym[v].
bit: u8
The power of two of the base.
This value defines bit() as bit.
pad: u8
The padding.
This value defines pad() as pad.
_phantom: PhantomData<T>
