macro_rules! track_try_unwrap {
    ($expr:expr) => { ... };
    ($expr:expr, $($format_arg:tt)*) => { ... };
}
Expand description

More human readable variant of the standard Result::unwrap method.

Examples

#[macro_use]
extern crate trackable;

use trackable::error::{Failed, Failure, ErrorKindExt};

fn main() {
   let result: Result<(), Failure> = Err(Failed.error().into());

   // Following two expressions are conceptually equivalent.
   result.clone().unwrap();
   track_try_unwrap!(result.clone());

   // `track_try_unwrap!()` can take additional arguments compatible to `format!()`.
   result.clone().expect(&format!("Additional information: {}", "foo"));
   track_try_unwrap!(result.clone(), "Additional information: {}", "foo");
}
