Enum olio::mem::MemAdvice

#[repr(u64)]
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.

impl Eq for MemAdvice

impl Clone for MemAdvice

fn clone(&self) -> MemAdvice

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
