bors f9fa13f705 Auto merge of #85746 - m-ou-se:io-error-other, r=joshtriplett ... Redefine `ErrorKind::Other` and stop using it in std. This implements the idea I shared yesterday in the libs meeting when we were discussing how to handle adding new `ErrorKind`s to the standard library: This redefines `Other` to be for *user defined errors only*, and changes all uses of `Other` in the standard library to a `#[doc(hidden)]` and permanently `#[unstable]` `ErrorKind` that users can not match on. This ensures that adding `ErrorKind`s at a later point in time is not a breaking change, since the user couldn't match on these errors anyway. This way, we use the `#[non_exhaustive]` property of the enum in a more effective way. Open questions: - How do we check this change doesn't cause too much breakage? Will a crate run help and be enough? - How do we ensure we don't accidentally start using `Other` again in the standard library? We don't have a `pub(not crate)` or `#[deprecated(in this crate only)]`. cc https://github.com/rust-lang/rust/pull/79965 cc `@rust-lang/libs` `@ijackson` r? `@dtolnay`		2021-07-02 09:01:42 +00:00
