Add stability inheritance This commit makes several changes to the stability index infrastructure: * Stability levels are now inherited lexically, i.e., each item's stability level becomes the default for any nested items. * The computed stability level for an item is stored as part of the metadata. When using an item from an external crate, this data is looked up and cached. * The stability lint works from the computed stability level, rather than manual stability attribute annotations. However, the lint still checks only a limited set of item uses (e.g., it does not check every component of a path on import). This will be addressed in a later PR, as part of issue #8962. * The stability lint only applies to items originating from external crates, since the stability index is intended as a promise to downstream crates. * The "experimental" lint is now _allow_ by default. This is because almost all existing crates have been marked "experimental", pending library stabilization. With inheritance in place, this would generate a massive explosion of warnings for every Rust program. The lint should be changed back to deny-by-default after library stabilization is complete. * The "deprecated" lint still warns by default. The net result: we can begin tracking stability index for the standard libraries as we stabilize, without impacting most clients. Closes #13540. 2014-06-12 00:23:11 +00:00			`// aux-build:lint_output_format.rs`
Change default lint output format. Since lint check attributes are the preferred way of selectively enabling/disabling lint checks, the output format of a failed default check has been changed to reflect that. When lint checks are being explicitly set by a command-line flag or an attribute, the behavior is unchanged, so that the user can quickly pinpoint the source. Closes #6580 2013-10-09 01:26:09 +00:00

Correctly handle path stability for 'use tree' items PR #5956 started checking the stability of path segments. However, this was not applied to 'use tree' items (e.g. 'use some::path::{ItemOne, ItemTwo}') due to the way that we desugar these items in HIR lowering. This PR modifies 'use tree' lowering to preserve resolution information, which is needed by stability checking. 2022-07-15 17:22:36 +00:00			`//~\| ERROR use of unstable library feature`
