Enum olio::mem::MemAdvice [−][src]
#[repr(usize)]pub enum MemAdvice { Normal, Random, Sequential, }
Memory access pattern advice.
This encodes a subset of POSIX.1-2001 madvise
flags, and is intending to
be a workable cross platform abstraction. In particular, the values do not
correspond to any libc or other lib constants, and are arranged in
ascending order of minimal to maximum priority in the presence of
concurrent interest in the same region.
