Encoder

cajeta.wire.Encoder — the bidirectional wire codec protocol for a T, and the zero-copy struct view that reads a wire record without decoding it. cajeta.wire ships the interfaces; the measured codec is a generated protobuf-wire-format implementation whose byte count equals protobuf’s own, produced from the same record description every competitor uses.

Benchmarks

Results

One chart per benchmark, for the machine selected at the top of the page. Languages are the bars, best first; Cajeta’s bar is in color and the competitors’ are gray. A skipped competitor keeps its row with the reason in place of a bar. A benchmark with no row on the selected machine says so and shows nothing else.

wire/encoder-encode

Not yet measured on Proton.
wire/encoder-decode

Not yet measured on Proton.
wire/struct-view-read

Not yet measured on Proton.

Reproduce

cd bench
./bench.sh --bench encoder-encode               # Cajeta
./bench.sh --bench encoder-encode --competitors # every pinned competitor

Every row records the compiler and competitor versions, flags, machine, OS and driver; METHODOLOGY states the rules a number must satisfy before it is published.
