Functions

func GetEnv

func GetEnv(envVar string, deflt string) string

func GetEnvAs

func GetEnvAs[T any](envVar string, deflt T, parser EnvParserFunc[T]) T

func InterfaceToStringArray

func InterfaceToStringArray(source interface{}) ([]string, error)

InterfaceToStringArray converts an interface{} that we know is a []string to that []string via []interface{}. This is useful when we have a map[string]interface{} and we want to get the []string{} out of it.

func LogDebugIfContextCancelled

func LogDebugIfContextCancelled(ctx context.Context, cleanupErr error, msg string)

LogDebugIfContextCanceled will ensure that LOG_LEVEL is set to debug if the context is canceled.

func NewDetachedContext

func NewDetachedContext(parent context.Context) context.Context

NewDetachedContext produces a new context that has a separate cancellation mechanism from its parent. This should be used when having to continue using a context after it has been canceled, such as cleaning up Docker resources after the context has been canceled but want to keep work associated with the same trace.

Types

type EnvParserFunc

type EnvParserFunc[T any] func(string) (T, error)
