Struct GuestPolicy 

#[repr(C)]
pub struct GuestPolicy(pub u32);

The firmware associates each guest with a guest policy that the guest owner provides. The firmware restricts what actions the hypervisor can take on the guest according to the guest policy. The policy also indicates the minimum firmware version to for the guest.

The guest owner provides the guest policy to the firmware during launch. The firmware then binds the policy to the guest. The policy cannot be changed throughout the lifetime of the guest. The policy is also migrated with the guest and enforced by the destination platform firmware.

Trait Implementations

impl<T> BitRange<T> for GuestPolicy

where u32: BitRange<T>,

fn bit_range(&self, msb: usize, lsb: usize) -> T

Get a range of bits.

fn set_bit_range(&mut self, msb: usize, lsb: usize, value: T)

Set a range of bits.

impl Clone for GuestPolicy

fn clone(&self) -> GuestPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GuestPolicy

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

Formats the value using the given formatter.

impl Default for GuestPolicy

fn default() -> GuestPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GuestPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GuestPolicy

fn eq(&self, other: &GuestPolicy) -> 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 Serialize for GuestPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for GuestPolicy
