//! # From on Into

/// Wrapper trait that is implemented on `Into` types.
///
/// This trait is purely needed for type parameter inferring purposes, where `Into` can not be used,
/// but `From` would make it not as versatile. This trait acts like `From`, but is implemented when
/// only `Into` is implemented.
