WebMay 15, 2024 · The Rust library implementation is fairly straightforward. As we did with our pure Python implementation, we initialize an array of counts for each possible byte value and iterate over the data to populate the counts. To finish the computation, we compute and return the negative sum of probabilities multiplied by the log2 of the probabilities. WebPanic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.. Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end.
