Macro pliron::arg_error

macro_rules! arg_error {
    ($loc: expr, $($t:tt)*) => { ... };
}

Create ErrorKind::InvalidArgument Error from any std::error::Error object. To create Result, use arg_err! instead. The macro also accepts format! like arguments to create one-off errors.

use thiserror::Error;
use pliron::{arg_error, result::{Result, ErrorKind, Error}, location::Location};

#[derive(Error, Debug)]
#[error("sample error")]
pub struct SampleErr;

assert!(
    matches!(
        arg_error!(Location::Unknown, SampleErr),
        Error {
           kind: ErrorKind::InvalidArgument,
           err,
           loc: _,
        } if err.is::<SampleErr>()
));

let res_msg: Error = arg_error!(Location::Unknown, "Some formatted {}", 0);
assert_eq!(
    res_msg.err.to_string(),
    "Some formatted 0"
);
