Types

type Resolver

type Resolver struct {
	// Backends is the raw map from style strings to backend constructors.
	Backends map[id.ID]backend2.Class
}

func (*Resolver) Probe

func (r *Resolver) Probe(ctx context.Context, sr service.Runner) ([]backend2.NamedSpec, error)

Probe probes every class in this resolver, and aggregates the specifications.

func (*Resolver) Resolve

func (r *Resolver) Resolve(cid id.ID) (backend2.Class, error)

Resolve tries to look up the backend specified by b in this resolver.
