Trap handler with CPU and bus access for HLE.

This is the recommended trait for high-level emulation: handlers get direct access to CPU state and the memory bus while a trap is being serviced. Return true to mark the trap as handled, or false to fall back to the real hardware exception.

Provided Methods

fn handle_aline( &mut self, _cpu: &mut CpuCore, _bus: &mut dyn AddressBus, _opcode: u16, ) -> bool

Handle an A-line trap (0xAxxx opcode).

fn handle_fline( &mut self, _cpu: &mut CpuCore, _bus: &mut dyn AddressBus, _opcode: u16, ) -> bool

Handle an F-line trap (0xFxxx opcode).

fn handle_trap( &mut self, _cpu: &mut CpuCore, _bus: &mut dyn AddressBus, _trap_num: u8, ) -> bool

Handle a TRAP #n instruction.

fn handle_breakpoint( &mut self, _cpu: &mut CpuCore, _bus: &mut dyn AddressBus, _bp_num: u8, ) -> bool

Handle a BKPT #n instruction.

fn handle_illegal( &mut self, _cpu: &mut CpuCore, _bus: &mut dyn AddressBus, _opcode: u16, ) -> bool

Handle an illegal instruction.

Dyn Compatibility

This trait is dyn compatible.

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