We add a Reset method which clears any internal state of an encoder or a decoder to let it be reused again as a new Writer or Reader respectively. We also export the encoder and decoder structs, renaming them to be Reader and Writer, and we guarantee that the underlying types from the constructors will always be Reader and Writer respectively. Benchmark results by reusing the encoder: on cpu: Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz name time/op Decoder/1e4-8 93.6µs ± 1% Decoder/1e-Reuse4-8 87.7µs ± 1% Decoder/1e5-8 877µs ± 1% Decoder/1e-Reuse5-8 860µs ± 3% Decoder/1e6-8 8.79ms ± 1% Decoder/1e-Reuse6-8 8.82ms ± 4% Encoder/1e4-8 168µs ± 2% Encoder/1e-Reuse4-8 160µs ± 1% Encoder/1e5-8 1.64ms ± 1% Encoder/1e-Reuse5-8 1.61ms ± 2% Encoder/1e6-8 16.2ms ± 6% Encoder/1e-Reuse6-8 15.8ms ± 2% name speed Decoder/1e4-8 107MB/s ± 1% Decoder/1e-Reuse4-8 114MB/s ± 1% Decoder/1e5-8 114MB/s ± 1% Decoder/1e-Reuse5-8 116MB/s ± 3% Decoder/1e6-8 114MB/s ± 1% Decoder/1e-Reuse6-8 113MB/s ± 5% Encoder/1e4-8 59.7MB/s ± 2% Encoder/1e-Reuse4-8 62.4MB/s ± 1% Encoder/1e5-8 61.1MB/s ± 1% Encoder/1e-Reuse5-8 62.0MB/s ± 2% Encoder/1e6-8 61.7MB/s ± 5% Encoder/1e-Reuse6-8 63.4MB/s ± 2% name alloc/op Decoder/1e4-8 21.8kB ± 0% Decoder/1e-Reuse4-8 50.0B ± 0% Decoder/1e5-8 21.8kB ± 0% Decoder/1e-Reuse5-8 70.4B ± 2% Decoder/1e6-8 21.9kB ± 0% Decoder/1e-Reuse6-8 271B ± 3% Encoder/1e4-8 77.9kB ± 0% Encoder/1e-Reuse4-8 4.17kB ± 0% Encoder/1e5-8 77.9kB ± 0% Encoder/1e-Reuse5-8 4.27kB ± 0% Encoder/1e6-8 77.9kB ± 0% Encoder/1e-Reuse6-8 5.22kB ± 0% name allocs/op Decoder/1e4-8 2.00 ± 0% Decoder/1e-Reuse4-8 1.00 ± 0% Decoder/1e5-8 2.00 ± 0% Decoder/1e-Reuse5-8 1.00 ± 0% Decoder/1e6-8 2.00 ± 0% Decoder/1e-Reuse6-8 1.00 ± 0% Encoder/1e4-8 3.00 ± 0% Encoder/1e-Reuse4-8 2.00 ± 0% Encoder/1e5-8 3.00 ± 0% Encoder/1e-Reuse5-8 2.00 ± 0% Encoder/1e6-8 3.00 ± 0% Encoder/1e-Reuse6-8 2.00 ± 0% Fixes #26535 Change-Id: Icde613fea6234a5bdce95f1e49910f5687e30b22 Reviewed-on: https://go-review.googlesource.com/c/go/+/273667 Trust: Agniva De Sarker <agniva.quicksilver@gmail.com> Trust: Joe Tsai <thebrokentoaster@gmail.com> Reviewed-by: Joe Tsai <thebrokentoaster@gmail.com> |
