Utility functions to create [mongodb](https://www.mongodb.com/) operator.

## Why

- IDE hint.

- Avoid typo.

- Type check for literal options.

- Shortcut for common operator combinations.

## Usage

```shell

go get github.com/NateScarlet/mongo-operators

```

```Go

import (

    "context"

    "github.com/mongodb/mongo-go-driver/mongo"

    "github.com/mongodb/mongo-go-driver/mongo/bson/primitive"

    q "github.com/NateScarlet/mongo-operators/pkg/query"

    a "github.com/NateScarlet/mongo-operators/pkg/aggregation"

)

type M = primitive.M

type A = primitive.A

func find(ctx context.Context, col *mongo.Collection) {

    col.FindOne(ctx, M{"name": q.In(A{"foo", "bar"})})

}

func update(ctx context.Context, col *mongo.Collection) {

    col.UpdateOne(ctx, M{}, q.MergeOperators(

        q.Set(M{"name": "foo"}),

        q.Push(M{"tags": "bar"}),

    ))

}

func aggregation(ctx context.Context, col *mongo.Collection) {

    col.Aggregate(ctx, A{

        a.Match(M{"name": "foo"}),

        a.Unwind("tags"),

    })

}

```
