Changes
rand_chachahas been replaced with a dependency onchacha20. This changes the implementation behindStdRng, but the output remains the same. There may be some API breakage when using the ChaCha-types directly as these are now the ones inchacha20instead ofrand_chacha(#1642).IndexedRandom::choose_multiple->sample,choose_multiple_array->sample_array,choose_multiple_weighted->sample_weighted, structSliceChooseIter->IndexedSamplesand fnsIteratorRandom::choose_multiple->sample,choose_multiple_fill->sample_fill(#1632)Fillbe implemented for element types, not sliceable types (#1652)OsError::raw_os_erroron UEFI targets by returningOption<usize>(#1665)TryRngCore::read_adapter(..) -> RngReadAdapterwith simpler structRngReader(#1669)SeedableRng::from_os_rng,try_from_os_rng(#1674)Clonesupport forStdRng,ReseedingRng(#1677)postcardinstead ofbincodeto test the serde feature (#1693)IteratorRandom::samplewhenamountis much larger than iterator size (#1695)os_rng->sys_rng,OsRng->SysRng,OsError->SysError(#1697)Rng->RngExtas upstreamrand_corehas renamedRngCore->Rng(#1717)Additions
