Trait Implementations

impl Clone for Size2M

fn clone(&self) -> Size2M

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Size2M

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Size2M

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MapSize for Size2M

fn ensure_chain_for<A: FrameAlloc, M: PhysMapper>( aspace: &AddressSpace<'_, M>, alloc: &mut A, va: VirtualAddress, nonleaf_flags: VirtualMemoryPageBits, ) -> Result<PhysicalPage<Size4K>, MapSizeEnsureChainError>

Ensure that the non-leaf chain for va exists down to the table that holds the leaf for Self, allocating and linking intermediate tables as needed.

fn set_leaf<M: PhysMapper>( aspace: &AddressSpace<'_, M>, leaf_tbl_page: PhysicalPage<Size4K>, va: VirtualAddress, pa: PhysicalAddress, leaf_flags: VirtualMemoryPageBits, )

Install the leaf entry for va → pa in the leaf_tbl_page returned by ensure_chain_for, with the given leaf_flags.

impl Ord for Size2M

fn cmp(&self, other: &Size2M) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PageSize for Size2M

const SIZE: u64 = 2_097_152u64

Page size in bytes (power of two).

const SHIFT: u32 = 21u32

log2(SIZE), i.e., number of low bits used for the offset.

impl PartialEq for Size2M

fn eq(&self, other: &Size2M) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Size2M

fn partial_cmp(&self, other: &Size2M) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
