Types

type ConstructorFn

type ConstructorFn func() any

Constructor function for creating new service records.

type Service

type Service struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Service structure.

To use:

1) Invoke `service.GetInstance` to access the singleton:

```go

svc := service.GetInstance

```

2a) Add your required service:

```go

svc.Add("SomeName", someInstance)

```

2b) Create your required service:

```go

svc.Create("SomeName", func() any { return NewThing() })

```

Profit.
