Struct gear_core :: pages :: PagesAmount Copy item path

impl<const SIZE: u32> PagesAmount<SIZE>

pub const SIZE: u32 = SIZE

Page size. May be any number power of two in interval [2, u32::MAX].

NOTE: In case SIZE == 0 or 1 or any not power of two number, then you would receive compilation error.

pub const UPPER: Self = _

Number of max pages amount. Equal to max page number + 1.

NOTE: const computation contains checking in order to prevent incorrect SIZE.

pub fn to_page_number(&self) -> Option<Page<SIZE>>

Get page number, which bounds this pages amount. If pages amount == 4GB size, then returns None, because such page number does not exist.

pub fn to_pages_amount<const S: u32>(&self) -> PagesAmount<S>

Returns corresponding amount of pages with another size S.

pub fn offset(&self) -> u64

Returns amount in bytes. Can be also considered as offset of a page with corresponding number. In 32-bits address space it can be up to u32::MAX + 1, so we returns u64 to prevent overflow.
