  "message": "rust: impl TrustedLen for VectorIter (#8797)\n\nImproves unpack performance for vectors by allowing the compiler\nto vectorize flatbuffers::Vector to std::vec::Vec conversions,\nusing the unstable trusted_len feature.\n\nInternally, enables an optimization in src/alloc/vec/spec_extend.rs:\nPreviously, unpacking a flatbuffers::Vector called\nSpecExtend::extend_desugared fallback, which inhibits vectorization\n(due to a branch before every element move).  Declaring TrustedLen\nallows SpecExtend::extend_trusted, which LLVM can often vectorize\ninto a memcpy.\n\nFor [ubyte] vectors in particular, this turns a rather expensive\nloop of \u0027mov BYTE PTR [rax+r13*1], bpl\u0027 into a `call memcpy`.",
