Types

type Mapper

type Mapper struct {
	// contains filtered or unexported fields
}

Mapper implements the lookup logic. It supports a limited form of path-segment and query-parameter mapping.

func New

func New() *Mapper

New constructs an empty Mapper.

func (*Mapper) Get

func (m *Mapper) Get(request *url.URL) (_ *db.Link, ok bool)

Get resolves an incoming request URL to a short link to redirect the caller to.

func (*Mapper) SetLinks

func (m *Mapper) SetLinks(links []*db.Link)

SetLinks updates the internal state of the Mapper with a new collection of short links. This method does not require external synchronization.
