Struct vm_memory::guest_memory::MemoryRegionOptions

pub struct MemoryRegionOptions {
    pub purpose: MemoryRegionPurpose,
    pub align: u64,
}

Fields

purpose: MemoryRegionPurpose

Some hypervisors (presently: Gunyah) need explicit knowledge about which memory region is used for protected firwmare, static swiotlb, or general purpose guest memory.

align: u64

Alignment for the mapping of this region. This intends to be used for arm64 KVM support where a block alignment is required for transparent huge-pages support

Implementations

impl MemoryRegionOptions

pub fn new() -> MemoryRegionOptions

pub fn purpose(self, purpose: MemoryRegionPurpose) -> Self

pub fn align(self, alignment: u64) -> Self

Trait Implementations

impl Clone for MemoryRegionOptions

fn clone(&self) -> MemoryRegionOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryRegionOptions

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

Formats the value using the given formatter.

impl Default for MemoryRegionOptions

fn default() -> MemoryRegionOptions

Returns the “default value” for a type.

impl Ord for MemoryRegionOptions

fn cmp(&self, other: &MemoryRegionOptions) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for MemoryRegionOptions

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for MemoryRegionOptions

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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