Required Associated Types§

type Error: StdError

Required Methods§

Source

fn read_registers(vcpu: &T) -> Result<<GdbArch as Arch>::Registers, Self::Error>

Reads vCPU’s registers.

Source

fn write_registers( vcpu: &T, regs: &<GdbArch as Arch>::Registers, ) -> Result<(), Self::Error>

Writes vCPU’s registers.

Source

fn read_memory( vcpu: &T, guest_mem: &GuestMemory, vaddr: GuestAddress, len: usize, ) -> Result<Vec<u8>, Self::Error>

Reads bytes from the guest memory.

Source

fn write_memory( vcpu: &T, guest_mem: &GuestMemory, vaddr: GuestAddress, buf: &[u8], ) -> Result<(), Self::Error>

Writes bytes to the specified guest memory.

Source

fn read_register( vcpu: &T, reg_id: <GdbArch as Arch>::RegId, ) -> Result<Vec<u8>, Self::Error>

Reads bytes from the guest register.

Returns an empty vector if reg_id is valid but the register is not available.

Source

fn write_register( vcpu: &T, reg_id: <GdbArch as Arch>::RegId, data: &[u8], ) -> Result<(), Self::Error>

Writes bytes to the specified guest register.

Source

fn enable_singlestep(vcpu: &T) -> Result<(), Self::Error>

Make the next vCPU’s run single-step.

Source

fn get_max_hw_breakpoints(vcpu: &T) -> Result<usize, Self::Error>

Get maximum number of hardware breakpoints.

Source

fn set_hw_breakpoints( vcpu: &T, breakpoints: &[GuestAddress], ) -> Result<(), Self::Error>

Set hardware breakpoints at the given addresses.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
