pub enum PosixFadviseAdvice

The specific advice provided to posix_fadvise.

Variants

POSIX_FADV_NORMAL = libc::POSIX_FADV_NORMAL: Revert to the default data access behavior.
POSIX_FADV_SEQUENTIAL = libc::POSIX_FADV_SEQUENTIAL: The file data will be accessed sequentially.
POSIX_FADV_RANDOM = libc::POSIX_FADV_RANDOM: A hint that file data will be accessed randomly, and prefetching is likely not advantageous.
POSIX_FADV_NOREUSE = libc::POSIX_FADV_NOREUSE: The specified data will only be accessed once and then not reused.
POSIX_FADV_WILLNEED = libc::POSIX_FADV_WILLNEED: The specified data will be accessed in the near future.
POSIX_FADV_DONTNEED = libc::POSIX_FADV_DONTNEED: The specified data will not be accessed in the near future.
