Enum pir_8_emu::binutils::pir_8_as::AssemblerDirectiveObeyError

pub enum AssemblerDirectiveObeyError<'s> {
    LabelNameTaken(&'s str),
    OutputAddressAlreadySet(u16, u16),
}

An error that could've occurred when obeying an asembly directive.

Examples

let mut next_output_address = Some(0x0110);
let mut labels = vec![("uwu".to_string(), 0x0069)].into_iter().collect();
assert_eq!(AssemblerDirective::SetOrigin(0x0420).obey(&mut next_output_address, &mut labels),
           Err(AssemblerDirectiveObeyError::OutputAddressAlreadySet(0x0110, 0x0420)));

assert_eq!(AssemblerDirective::SaveLabel("uwu").obey(&mut next_output_address, &mut labels),
           Err(AssemblerDirectiveObeyError::LabelNameTaken("uwu")));

Variants

LabelNameTaken(&'s str)

The label wit hthe specified name already exists

OutputAddressAlreadySet(u16, u16)

An origin was attempted to be specified with the output address already existing

First argument is the current output address, the second – the requested

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
