Functions

func CreateJobsFromStrings

func CreateJobsFromStrings(values []string) []interface{}

CreateJobsFromStrings is an utility to create jobs from an slice of strings.

func ForEach

func ForEach(ctx context.Context, jobs []interface{}, concurrency int, jobFunc func(ctx context.Context, job interface{}) error) error

ForEach runs the provided jobFunc for each job up to concurrency concurrent workers. The execution breaks on first error encountered.

func ForEachUser

func ForEachUser(ctx context.Context, userIDs []string, concurrency int, userFunc func(ctx context.Context, userID string) error) error

ForEachUser runs the provided userFunc for each userIDs up to concurrency concurrent workers. In case userFunc returns error, it will continue to process remaining users but returns an error with all errors userFunc has returned.

Types

type SyncBuffer

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

SyncBuffer is a io.writer implementation with atomic writes. It only keeps data in memory.

func (*SyncBuffer) String

func (sb *SyncBuffer) String() string

func (*SyncBuffer) Write

func (sb *SyncBuffer) Write(p []byte) (n int, err error)
