🔬This is a nightly-only experimental API. (stdsimd)
Available on x86-64 only.
Expand description

Rotate the bits in each packed 64-bit integer in a to the right by the number of bits specified in imm8, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
