Required Methods§

Source

fn bit_mask_range(start: u32, end: u32) -> Self

Returns a bitmask of ones from the [start..=end] range.

Sets the rest of the bits to 0.

§Panics

Panics in debug mode if start >= BITS || end >= BITS || start > end.

§Benchmarks

The current algorithm used can be more than 1 order of magnitude more efficient than a naive loop that sets the individual bits, as well as much more consistant across the spectrum of bitsizes.

The following table shows the compared benchmark for start=0 and end=BITS-1 measured on an i5-8350U CPU @ 1.70 Ghz:
