Enum allocator_suite::memory_sources::mmap::huge_page_size::HugePageSize

#[repr(i32)]
pub enum HugePageSize {
    None,
}

Request that an allocation uses huge pages.

The allocation being requested has to be aligned to the size requested, viz it is best to only make allocations that use the configured huge page size.

On x86-64, this should be 2Mb or 1Gb.

Currently such requests assume that transparent huge pages are in effect.

On operating systems other than Android and Linux, huge page size has no effect.

Variants

None

Regular, non-huge-page.
