segmentio

aarv segmentio codec

A drop-in JSON codec for aarv backed by github.com/segmentio/encoding/json, a faster, allocation-friendly replacement for encoding/json that keeps full behavioral compatibility with the standard library.

When to use it

• You want a meaningful speedup over encoding/json without changing tags or struct shapes.
• You need pure-Go portability (works on every architecture Go supports).
• You don't want JIT warmup or any of sonic's platform constraints.

Install

go get github.com/nilshah80/aarv/codec/segmentio

This codec lives in its own Go module so the main aarv module stays dependency-free.

Usage

import (
    "github.com/nilshah80/aarv"
    "github.com/nilshah80/aarv/codec/segmentio"
)

app := aarv.New(aarv.WithCodec(segmentio.New()))

That's it — every c.JSON(...) and request-body bind on the app now goes through segmentio's encoder.

Notes

• Behavior matches encoding/json, including struct tags, json.Marshaler, and omitempty.
• Recorded head-to-head numbers against sonic and jsonv2 live in ../benchmarks/RESULTS.md. The suite is its own Go module — reproduce with cd codec/benchmarks && go test -bench=. -benchmem ./... (running from the repo root will not work).
