Function qt_core::q_count_leading_zero_bits_u32

pub unsafe fn q_count_leading_zero_bits_u32(v: u32) -> c_uint

Returns the number of consecutive zero bits in v, when searching from the MSB. For example, qCountLeadingZeroBits(quint32(1)) returns 31 and qCountLeadingZeroBits(quint32(8)) returns 28.

Calls C++ function: unsigned int qCountLeadingZeroBits(quint32 v).

C++ documentation:
