### Main Configuration Structs

```go
type Endpoint struct {
	URL         string
	Username    string
	Token       string
	BearerToken string
	SkipTLSVerify bool
}

type Config struct {
	Source       Endpoint
	Target       Endpoint
	Branches     []string
	Mappings     []RefMapping
	IncludeTags  bool
	DryRun       bool
	Verbose      bool
	ShowStats    bool
	MeasureMemory bool
	Force        bool
	Prune        bool
	MaxPackBytes int64
	BatchMaxPackBytes int64
	ProtocolMode string
}

... // Other struct definitions
```

### Sample Usage Functionality

```go
func (r FetchResult) MarshalJSON() ([]byte, error) {
	type fetchResultJSON struct {
		SourceURL      string    `json:"source_url"`
		RequestedMode  string    `json:"requested_mode"`
		Protocol       string    `json:"protocol"`
		Wants          []RefInfo `json:"wants"`
		Haves          []string  `json:"haves"`
		FetchedObjects int       `json:"fetched_objects"`
		Stats          Stats     `json:"stats"`
	}
	...
}
```
