Struct AddressSpaceLayout

pub struct AddressSpaceLayout {
    pub phys_end: u64,
    pub mem_start: u64,
    pub mem_end: u64,
    pub usable_end: u64,
}

Address space layout configuration.

The layout configuration must guarantee that mem_start <= mem_end <= phys_end. Non-memory region should be arranged into the range [mem_end, phys_end).

Fields

phys_end: u64

end of guest physical address

mem_start: u64

start of guest memory address

mem_end: u64

end of guest memory address

usable_end: u64

end of usable memory address

Implementations

impl AddressSpaceLayout

pub fn new(phys_end: u64, mem_start: u64, mem_end: u64) -> Self

Create a new instance of AddressSpaceLayout.

pub fn is_region_valid(&self, region: &AddressSpaceRegion) -> bool

Check whether an region is valid with the constraints of the layout.

Trait Implementations

impl Clone for AddressSpaceLayout

fn clone(&self) -> AddressSpaceLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AddressSpaceLayout

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

Formats the value using the given formatter.

impl PartialEq for AddressSpaceLayout

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

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

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

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