Macro pliron::verify_error

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

To create Result, use verify_err! instead. The macro also accepts format! like arguments to create one-off errors.

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

           err,
           loc: _,
        } if err.is::<SampleErr>()
));

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