Typedef Documentation

◆ BitInt

using blender::bits::BitInt = uint64_t

Using a large integer type is better because then it's easier to process many bits at once.

◆ bits_to_index_ranges()

template<typename IntT>

Extracts index ranges from the given bits. For example 00111011 would result in two ranges: [2-4], [6-7].

It's especially optimized to handle cases where there are very many or very few set bits.

◆ is_bounded_span()

bool blender::bits::is_bounded_span ( const BitSpan span)

Checks if the span fulfills the requirements for a bounded span. Bounded spans can often be processed more efficiently, because fewer cases have to be considered when aligning multiple such spans.

See comments in the function for the exact requirements.

Don't allow small sized spans to cross BitInt boundaries.

◆ or_bools_into_bits()

bool blender::bits::or_bools_into_bits ( Span< bool > bools,

Converts the bools to bits and ors them into the given bits. For pure conversion, the bits should therefore be zero initialized before they are passed into this function.

Parameters
allowed_overshootHow many bools/bits can be read/written after the end of the given spans. This can help with performance because the internal algorithm can process many elements at once.
Returns
True if any of the checked bools were true (this also includes the bools in the overshoot).
