  "message": "Remove exception WRT same-crate `non_exhaustive` reads\n\nWhen matching against a single-variant enum marked `non_exhaustive`\nand defined in a different crate, we pretend that there might be\nmultiple variants and force a read of the discriminant.  In [Rust PR\n150681], we decided to remove the same-crate exception.  Now matching\nagainst a single-variant `non_exhaustive` enum in the same crate will\nalso cause a discriminant read.\n\nSeparately, prior to [Rust PR 150681], `rustc` was eliding the\ndiscriminant read when an enum has only one *inhabited* variant.  This\ncontradicts what the Reference says in:\n\n\u003e r[type.closure.capture.precision.discriminants.uninhabited-variants]\n\u003e\n\u003e Even if all variants but the one being matched against are\n\u003e uninhabited, making the pattern [irrefutable][patterns.refutable],\n\u003e the discriminant is still read if it otherwise would be.\n\nWe decided with our lang FCP to confirm the behavior already encoded\nin the Reference, so no change is needed there.\n\n[Rust PR 150681]: https://github.com/rust-lang/rust/pull/150681\n",
