# Unwrapping Results With Compile-Time Guarantee of Infallibility

The Rust standard type `Result` sometimes occurs parameterized
with an error type that has no possible values, such as
`std::convert::Infallible`. Consequently, calling the `unwrap` method on a
`Result` value of such a type will never panic.
Therein lies a maintainability hazard: if the error parameter type is later
changed to one that can represent actually occurring errors, those uses of
`unwrap` that could previously be relied upon to be infallible, quietly
become liable to panic.

To help prevent this from happening without a compile-time safeguard,
this crate provides an alternative method `unwrap_infallible` that shall only
be available for `Result` values with a known-impossible `Err` variant.
