Encoder and Decoder Codec for decimal.Decimal{} as primitive.Decimal128 on official mongo-go-driver

Usage

import (
    ...
    "github.com/muktihari/decimalcodec"
)

func main() {
    rb := bsoncodec.NewRegistryBuilder()

    // you might want to include defaults encoder and decoder as well
    bsoncodec.DefaultValueDecoders{}.RegisterDefaultDecoders(rb)
    bsoncodec.DefaultValueEncoders{}.RegisterDefaultEncoders(rb)

    decimalcodec.RegisterEncodeDecoder(rb)
    
    registry := rb.Build()
    
    client, err := mongo.Connect(context.Background(),
        options.Client().
            ApplyURI("mongodb://localhost:27017").
            SetRegistry(registry),
    )
    ...
