#[repr(u8)]pub enum Advice {
    Normal = 0,
    Sequential = 1,

}

Expand description

File or memory access pattern advisory information.

Variants§

§

Normal = 0

The application has no advice to give on its behavior with respect to the specified data.

§

Sequential = 1

The application expects to access the specified data sequentially from lower offsets to higher offsets.

§

Random = 2

The application expects to access the specified data in a random order.

§

WillNeed = 3

The application expects to access the specified data in the near future.

§

DontNeed = 4

The application expects that it will not access the specified data in the near future.

§

NoReuse = 5

The application expects to access the specified data once and then not reuse it thereafter.
