  "message": "Introduce absl::TransparentHash for transparent hashing of multiple types.\n\nabsl::TransparentHash\u003cTs...\u003e is a hash functor that can hash any of the types Ts... It is marked as transparent (is_transparent \u003d void). This allows containers like absl::flat_hash_map to use a single hash functor for lookups with different but comparable types (e.g., std::string and absl::string_view).\n\nAdded a test case in absl/hash/hash_test.cc using Name and NameView to demonstrate and test absl::TransparentHash with a custom transparent equality functor.\n\n```\nname                 cpu/op       cpu/op     vs base\nBM_TransparentFind   2.620n ± 1%   2.413n ± 1%  -7.90% (p\u003d0.002 n\u003d6)\n\nname                 time/op       time/op     vs base\nBM_TransparentFind   2.625n ± 1%   2.418n ± 1%  -7.87% (p\u003d0.002 n\u003d6)\n\nname                 INSTRUCTIONS/op  INSTRUCTIONS/op  vs base\nBM_TransparentFind    45.07 ± 0%        42.07 ± 0%  -6.67% (p\u003d0.002 n\u003d6)\n\nname                 CYCLES/op   CYCLES/op   vs base\nBM_TransparentFind    9.229 ± 0%   8.492 ± 0%  -7.98% (p\u003d0.002 n\u003d6)\n```\n\nPiperOrigin-RevId: 975251791\nChange-Id: I7400e103167d707366f0be82dce627ab478959dd\n",
