Module bitvec::order [−][src]
Expand description
Ordering of bits within register elements.
bitvec structures are parametric over any ordering of bits within a register.
The BitOrder trait maps a cursor position (indicated by the BitIdx type) to an
electrical position (indicated by the BitPos type) within that element, and
also defines the order of traversal over a register.
The only requirement on implementors of BitOrder is that the transform function
from cursor (BitIdx) to position (BitPos) is total (every integer in the
domain 0 .. T::BITS is used) and unique (each cursor maps to one and only
one position, and each position is mapped by one and only one cursor).
Contiguity is not required.
BitOrder is a stateless trait, and implementors should be zero-sized types.
