  "message": "fix: Crash when hovering on anonymous consts\n\nPreviously, the following code would cause rust-analyzer to infinitely\nrecurse when hovering on `x`.\n\n    trait Tr\u003cconst N: usize\u003e {}\n    pub fn f(x: impl Tr\u003c{ 0 }\u003e) {}\n\nAttaching gdb and printing a stack trace shows that the problem is in\nHirDisplay for an anonymous const.\n\n    frame 9  hir_ty::display::hir_fmt_generic_arguments () at crates/hir-ty/src/display.rs:1920\n    frame 10 0x00005555563b9f94 in hir_ty::display::hir_fmt_generics () at crates/hir-ty/src/display.rs:1843\n    frame 11 0x00005555563bd0ea in \u003chir_ty::next_solver::consts::Const as hir_ty::display::HirDisplay\u003e::hir_fmt () at crates/hir-ty/src/display.rs:768\n    frame 12 0x00005555563ba964 in \u003chir_ty::next_solver::generic_arg::GenericArg as hir_ty::display::HirDisplay\u003e::hir_fmt () at crates/hir-ty/src/display.rs:716\n    frame 13 hir_ty::display::hir_fmt_generic_arguments () at crates/hir-ty/src/display.rs:1920\n\nInstead, just render anonymous consts as `{const}` rather than trying\nto render the synthetic type parameters too.\n\n(We could track cycles like we do for recursive bounds, but that just\nproduces a hover of `x: impl Tr\u003c{const}\u003cimpl …\u003e\u003e + ?Sized` which\ndoesn\u0027t seem terribly useful.)\n\nAI disclosure: Initial implementation done with Codex and GPT-5.5.\n",
