Enum pir_8_emu::micro::MicroOpPerformError

pub enum MicroOpPerformError {
    MicrostackUnderflow,
    InvalidMicrostackTop(u8, &'static [u8]),
}

An error that could've occurred when performing a μOp.

Examples

assert_eq!(MicroOp::StackPush.perform(&mut vec![], &mut memory, &mut ports, &mut registers,
                                      &mut pc, &mut sp, &mut adr, &mut ins),
           Err(MicroOpPerformError::MicrostackUnderflow));

Variants

MicrostackUnderflow

The microstack had too few elements for the μOp being performed

InvalidMicrostackTop(u8, &'static [u8])

The top of the microstack had a value outside the domain of the μOp being performed

impl Eq for MicroOpPerformError

impl Error for MicroOpPerformError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Hash for MicroOpPerformError

fn hash<__H: Hasher>(&self, state: &mut __H)

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].
