- set 1.62 Rust as MSRV - use new fmt syntax where possible - refactor `.to_owned()`, `.to_string()` and `.into()` usage - rename `IntoResolvable::into()` as `IntoResolvable::into_resolvable()` to disambiguate with `Into::into()` - use `#[derive(Default)]` for enums where possible - use `bool::then_some()` where possible
