Command-line arguments are mapped to Go values via the Mapper interface: Command-line arguments are mapped to Go values via the Mapper interface:
```go ```go
// A Mapper knows how to map command-line input to Go. // A Mapper represents how a field is mapped from command-line values to Go.
//
// Mappers can be associated with concrete fields via pointer, reflect.Type, reflect.Kind, or via a "type" tag.
//
// Additionally, if a type implements the MapperValue interface, it will be used.
type Mapper interface { type Mapper interface {
// Decode scan into target. // Decode ctx.Value with ctx.Scanner into target.
// Decode(ctx *DecodeContext, target reflect.Value) error
// "ctx" contains context about the value being decoded that may be useful
// to some mappers.
Decode(ctx *MapperContext, scan *Scanner, target reflect.Value) error
} }
``` ```
