# rust-eh

This is an error handling experiment.  Primarily it tries to bring the

debuggability of Python tracebacks to Rust results.

Current status:

```

Traceback (most recent cause last):

  File "/Users/mitsuhiko/Development/rust-eh/examples/test.rs", line 42

    fail!(FileNotFound { file: Some(Path::new("/missing.txt")) });

  File "/Users/mitsuhiko/Development/rust-eh/examples/test.rs", line 46

    try!(test());

File not found: Failed to locate file (file=/missing.txt)

The above error resulted in another:

Traceback (most recent cause last):

  File "/Users/mitsuhiko/Development/rust-eh/examples/test.rs", line 52

    Err(err) => fail!(RecordNotFound, "could not find record", err),

Record not found: could not find record

```
