pub trait ExecutionBackend: Send {
    // Required methods
    fn reset(&mut self, config: &MachineConfig) -> Result<()>;
    fn step(&mut self) -> Result<bool>;
    fn read_memory(&self, address: u64, buffer: &mut [u8]) -> Result<()>;

}

Required Methods§

Source

fn reset(&mut self, config: &MachineConfig) -> Result<()>

Source

fn step(&mut self) -> Result<bool>

Source

fn read_memory(&self, address: u64, buffer: &mut [u8]) -> Result<()>

Source

fn write_memory(&mut self, address: u64, data: &[u8]) -> Result<()>

Provided Methods§

Source

fn restore_state(&mut self, _state: &SavedState) -> Result<()>

Restore an attached v86 saved state after reset. Backends that do not support saved states may keep the default no-op implementation.

Source

fn vga_framebuffer_rgb(&self) -> Option<(u32, u32, Vec<u8>)>

Return the current guest framebuffer as packed RGB bytes when the backend exposes a graphical VGA mode.

Source

fn inject_text(&mut self, _text: &str) -> Result<usize>

Queue host text as guest keyboard input when supported by the backend.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
