Macro arg_err 

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

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

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

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

assert!(
    matches!(
        arg_err!(Location::Unknown, SampleErr),
        Result::<()>::Err(Error {
           kind: ErrorKind::InvalidArgument,
           err,
           ..
        }) if err.is::<SampleErr>()
));

let res_msg: Result<()> = arg_err!(Location::Unknown, "Some formatted {}", 0);
assert_eq!(
    res_msg.unwrap_err().err.to_string(),
    "Some formatted 0"
);
