Discrete labels

Labels are countable, comparable and hashable. Currently null-type (no targets), boolean (binary task) and usize, strings (multi-label tasks) are supported.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
