Lorenz Bauer 04bf36e973 encoding/binary: add Append, Encode and Decode ... Add a function which appends the binary representation of a value to the end of a slice. This allows users to encode values with zero allocations. Also add Encode and Decode functions which mimic unicode/utf8. goos: darwin goarch: arm64 pkg: encoding/binary cpu: Apple M1 Pro │ base.txt │ append.txt │ │ sec/op │ sec/op vs base │ ReadSlice1000Int32s-10 2.690µ ± 0% 2.532µ ± 3% -5.86% (p=0.002 n=6) ReadStruct-10 205.8n ± 0% 201.4n ± 1% -2.14% (p=0.002 n=6) WriteStruct-10 159.1n ± 0% 153.5n ± 0% -3.55% (p=0.002 n=6) WriteSlice1000Structs-10 129.8µ ± 0% 124.2µ ± 0% -4.34% (p=0.002 n=6) ReadSlice1000Structs-10 161.7µ ± 0% 160.3µ ± 0% -0.89% (p=0.002 n=6) ReadInts-10 156.8n ± 0% 161.6n ± 0% +3.09% (p=0.002 n=6) WriteInts-10 134.5n ± 0% 139.5n ± 2% +3.72% (p=0.002 n=6) WriteSlice1000Int32s-10 2.691µ ± 16% 2.551µ ± 4% -5.20% (p=0.002 n=6) PutUint16-10 0.6448n ± 4% 0.6212n ± 1% ~ (p=0.093 n=6) AppendUint16-10 1.414n ± 0% 1.424n ± 1% ~ (p=0.115 n=6) PutUint32-10 0.6210n ± 0% 0.6211n ± 0% ~ (p=0.833 n=6) AppendUint32-10 1.414n ± 0% 1.426n ± 1% +0.85% (p=0.017 n=6) PutUint64-10 0.6210n ± 0% 0.6394n ± 1% +2.95% (p=0.002 n=6) AppendUint64-10 1.414n ± 0% 1.427n ± 2% ~ (p=0.052 n=6) LittleEndianPutUint16-10 0.6239n ± 0% 0.6271n ± 1% ~ (p=0.063 n=6) LittleEndianAppendUint16-10 1.421n ± 0% 1.432n ± 1% +0.81% (p=0.002 n=6) LittleEndianPutUint32-10 0.6240n ± 0% 0.6240n ± 0% ~ (p=0.766 n=6) LittleEndianAppendUint32-10 1.422n ± 1% 1.425n ± 0% ~ (p=0.673 n=6) LittleEndianPutUint64-10 0.6242n ± 0% 0.6238n ± 0% -0.08% (p=0.030 n=6) LittleEndianAppendUint64-10 1.420n ± 0% 1.449n ± 1% +2.04% (p=0.002 n=6) ReadFloats-10 39.36n ± 0% 42.54n ± 1% +8.08% (p=0.002 n=6) WriteFloats-10 33.65n ± 0% 35.27n ± 1% +4.80% (p=0.002 n=6) ReadSlice1000Float32s-10 2.656µ ± 0% 2.526µ ± 1% -4.91% (p=0.002 n=6) WriteSlice1000Float32s-10 2.765µ ± 0% 2.857µ ± 3% +3.31% (p=0.002 n=6) ReadSlice1000Uint8s-10 129.1n ± 1% 130.4n ± 1% ~ (p=0.126 n=6) WriteSlice1000Uint8s-10 144.90n ± 3% 18.67n ± 2% -87.12% (p=0.002 n=6) PutUvarint32-10 12.11n ± 0% 12.12n ± 0% ~ (p=0.675 n=6) PutUvarint64-10 30.82n ± 0% 30.79n ± 1% ~ (p=0.658 n=6) AppendStruct-10 107.8n ± 0% AppendSlice1000Structs-10 119.0µ ± 0% AppendInts-10 55.29n ± 0% AppendSlice1000Int32s-10 2.211µ ± 1% geomean 33.07n 48.18n -7.03% Fixes #60023 Change-Id: Ife3f217b11d5f3eaa5a53fe8a7e877552f751f94 Reviewed-on: https://go-review.googlesource.com/c/go/+/579157 Reviewed-by: Keith Randall <khr@google.com> Auto-Submit: Austin Clements <austin@google.com> Reviewed-by: Ingo Oeser <nightlyone@googlemail.com> Reviewed-by: Austin Clements <austin@google.com> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com>		2024-05-20 18:58:26 +00:00
