Enum AccessPattern

pub enum AccessPattern {
    Normal,
    Random,
    Sequential,
}

Values supported by ByteView::hint.

This is largely an abstraction over madvise(2) and fadvise(2).

Variants

Normal

No special treatment.

The operating system is in full control of the buffer, a generally good default.

This is the default.

Random

Expect access to be random.

Read ahead might be less useful than normally.

Sequential

Expect access to be in sequential order, read ahead might be very useful. After reading data there is a high chance it will not be accessed again and can be aggressively freed.
