Struct test_runner::GdbRunner

pub struct GdbRunner(/* private fields */);

Show test output in GDB, using the File I/O Protocol (called HIO in some 3DS homebrew resources). Both stdout and stderr will be printed to the GDB console.

Creating this runner at the beginning of a doctest enables output from failing tests. Without GdbRunner, tests will still fail on panic, but they won’t display anything written to stdout or stderr.

The runner should remain in scope for the remainder of the test.

Examples

```
let _runner = test_runner::GdbRunner::default();
assert_eq!(2 + 2, 4);
```

```should_panic
let _runner = test_runner::GdbRunner::default();
assert_eq!(2 + 2, 5);
```
