Struct RunConfig 

pub struct RunConfig {
    pub instct: i64,
    pub time_divisor: u32,
    pub fixed_update: bool,
    pub do_sleep: bool,
    pub single_step: bool,
    pub trace: Option<Box<dyn Write>>,
}

Parameters that control the Emulator::run loop.

Fields

instct: i64

Maximum number of instructions to execute. -1 means unlimited.

time_divisor: u32

Time divisor applied to wall-clock time before feeding the CLINT timer. 1 = real time. Values > 1 make the CPU appear slower, which is useful for deterministic testing (-l locks it to the instruction counter).

fixed_update: bool

When true, the cycle counter is used as the time base instead of wall-clock time. Produces fully deterministic execution.

do_sleep: bool

When true, the run loop calls Platform::mini_sleep during WFI to avoid burning host CPU. Disable with -p for maximum throughput.

single_step: bool

When true, execute one instruction per loop iteration and call Emulator::dump_state after each one. Enabled by -s.

trace: Option<Box<dyn Write>>

Optional writer for the compact execution trace (--trace <FILE>). When Some, every instruction is logged with the registers it modified.

Trait Implementations

impl Default for RunConfig

fn default() -> Self
