`client-go` is a library to access [Service Binding Specification for Kubernetes](https://k8s-service-bindings.github.io/spec/) conformant Service Binding [Workload Projections](https://k8s-service-bindings.github.io/spec/#workload-projection).

## Example

```golang

import (

	"context"

	"fmt"

	"github.com/jackc/pgx/v4"

	"github.com/nebhale/client-go/bindings"

	"os"

)

func main() {

	b := bindings.FromServiceBindingRoot()

	b = bindings.Filter(b, "postgresql")

	if len(b) != 1 {

		_, _ = fmt.Fprintf(os.Stderr, "Incorrect number of PostgreSQL drivers: %d\n", len(b))

		os.Exit(1)

	}

	u, ok := bindings.Get(b[0], "url")

	if !ok {

		_, _ = fmt.Fprintln(os.Stderr, "No URL in binding")

		os.Exit(1)

	}

	conn, err := pgx.Connect(context.Background(), u)

	if err != nil {

		_, _ = fmt.Fprintf(os.Stderr, "Unable to connect to database: %v\n", err)

		os.Exit(1)

	}

	defer conn.Close(context.Background())

	// ...

}
