Types

type SchemeMap

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

SchemeMap maps URL schemes to values. The zero value is an empty map, ready for use.

func (*SchemeMap) FromString

func (m *SchemeMap) FromString(typ, urlstr string) (any, *url.URL, error)

FromString parses urlstr as an URL and looks up the value for the URL's scheme.

func (*SchemeMap) FromURL

func (m *SchemeMap) FromURL(typ string, u *url.URL) (any, error)

FromURL looks up the value for u's scheme.

func (*SchemeMap) Register

func (m *SchemeMap) Register(api, typ, scheme string, value any)

Register registers scheme for value; subsequent calls to FromString or FromURL with scheme will return value. api is the portable API name (e.g., "blob"); the same value should always be passed. It should be in all lowercase. typ is the portable type (e.g., "Bucket"). Register panics if scheme has already been registered.

func (*SchemeMap) Schemes

func (m *SchemeMap) Schemes() []string

Schemes returns a sorted slice of the registered schemes.

func (*SchemeMap) ValidScheme

func (m *SchemeMap) ValidScheme(scheme string) bool

ValidScheme returns true iff scheme has been registered.
