=== Description

*Template Parameters*

|===

|`K`
| Number of bits set/checked per operation. Must be greater than zero.

|===

`fast_multiblock64<K>` is statistically equivalent to
`xref:multiblock[multiblock]<std::uint64_t, K>`, but takes advantage
of selected SIMD technologies, when available at compile time, to perform faster.
Currently supported: AVX2.
The non-SIMD case falls back to regular `multiblock`.

`xref:subfilters_used_value_size[_used-value-size_]<fast_multiblock64<K>>` is
`8 * K`.
