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
