Nick Torres	91d8a804d3	result_map_or_into_option: add lint to catch manually adpating Result -> Option ... Result<T, E> has an `ok()` method that adapts a Result<T,E> into an Option<T>. It's possible to get around this adapter by writing Result<T,E>.map_or(None, Some). This lint is implemented as a new variant of the existing [`option_map_none` lint](https://github.com/rust-lang/rust-clippy/pull/2128)	2020-04-04 03:17:13 -07:00
