Implementations

impl Vcpu

pub fn new() -> Result<Self>

pub fn get_pending_interrupt(&self, intr: InterruptType) -> Result<bool>

Gets pending interrupts for a vCPU.

pub fn set_pending_interrupt(
    &self,
    intr: InterruptType,
    pending: bool
) -> Result<()>

Sets pending interrupts for a vCPU.

pub fn get_reg(&self, reg: Reg) -> Result<u64>

Gets the value of a vCPU general purpose register.

pub fn set_reg(&self, reg: Reg, value: u64) -> Result<()>

Sets the value of a vCPU general purpose register.

pub fn get_simd_fp_reg(&self, reg: SimdFpReg) -> Result<i8x16>

Gets the value of a vCPU floating point register

pub fn set_simd_fp_reg(&self, reg: SimdFpReg, value: i8x16) -> Result<()>

Sets the value of a vCPU floating point register

pub fn get_sys_reg(&self, reg: SysReg) -> Result<u64>

Gets the value of a vCPU system register.

pub fn set_sys_reg(&self, reg: SysReg, value: u64) -> Result<()>

Sets the value of a vCPU general purpose register.

pub fn get_trap_debug_exceptions(&self) -> Result<bool>

Gets whether debug exceptions exit the guest.

pub fn set_trap_debug_exceptions(&self, value: bool) -> Result<()>

Sets whether debug exceptions exit the guest.

pub fn get_trap_debug_reg_accesses(&self) -> Result<bool>

Gets whether debug-register accesses exit the guest.

pub fn set_trap_debug_reg_accesses(&self, value: bool) -> Result<()>

Sets whether debug-register accesses exit the guest.

pub fn get_exec_time(&self) -> Result<u64>

Returns the cumulative execution time of a vCPU, in nanoseconds.

pub fn get_vtimer_mask(&self) -> Result<bool>

Gets the virtual timer mask.

pub fn set_vtimer_mask(&self, vtimer_is_masked: bool) -> Result<()>

Sets or clears the virtual timer mask.

pub fn get_vtimer_offset(&self) -> Result<u64>

Returns the vTimer offset for the vCPU ID you specify.

pub fn set_vtimer_offset(&self, vtimer_offset: u64) -> Result<()>

Sets the vTimer offset to a value that you provide.

Trait Implementations

impl Clone for Vcpu

fn clone(&self) -> Vcpu

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Vcpu

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

Formats the value using the given formatter.

impl Display for Vcpu

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

Formats the value using the given formatter.

impl Drop for Vcpu

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq<Vcpu> for Vcpu

fn eq(&self, other: &Vcpu) -> 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.
