Functions

func Map

func Map(
	ctx context.Context,
	m Mapper,
	inputs []interface{},
	numWorkers int,
) (outputs []interface{}, err error)

Map applies m.Map to inputs using numWorkers goroutines. Collects the outputs or stops early if error is encountered.

Types

type Mapper

type Mapper interface {
	Map(ctx context.Context, input interface{}) (output interface{}, err error)
}

Mapper maps inputs into outputs.

type MapperFunc

type MapperFunc func(ctx context.Context, input interface{}) (output interface{}, err error)

MapperFunc is an adaptor to allow the use of ordinary functions as Mappers.

func (MapperFunc) Map

func (f MapperFunc) Map(ctx context.Context, input interface{}) (output interface{}, err error)

Map calls f.
