Crate failure [−] [src]

An experimental new error handling library.

The primary items exported by this library are:

• Fail: a new trait for custom error types in Rust.
• Error: a wrapper around Fail types to make it easy to coallesce them at higher levels.

As a general rule, library authors should create their own error types and implement Fail for them, whereas application authors should primarily deal with the Error type. There are exceptions to this rule, though, in both directions, and users should do whatever seems most appropriate to their situation.
