miniunchecked

A crate with some utility methods for debug unchecked operations on Option, Result and slice / str, as well as a debug unreachable! alternative.

A middle ground between someting like

• calling Option::unwrap() / Result::unwrap() / slice/string square brackets indexing operator, or using unreachable!, which always panic if None / Err / out of bounds / reached, and
• unsafe Option::unwrap_unchecked() Result::unwrap_unchecked() / [T]::get_unchecked(), or using unreachable_unchecked(), which never panic and lead to UB when None / Err / out of bounds,

an operation which does unsafe access in release configuration, for optimal codegen if the invariants are maintained by other means, but also panics on None / Err / out of bounds index in debug configuration / when running tests.
