Functions ¶
func Cancellable ¶
Cancellable returns an iterator over seq but it also checks if ctx is cancelled each n elements seq yields.
func Cancellable2 ¶
Cancellable2 returns an iterator over seq but it also checks if ctx is cancelled each n elements seq yields.
func Clone2 ¶
Clone2 maps seq by slices.Clone.
func Collect ¶
Collect maps seq by slices.Collect.
func Collect2 ¶
Collect2 maps seq by slices.Collect.
func HandleErr ¶
HandleErr returns an iterator over only former value of seq. If latter value the seq yields is non-nil then it calls handle. If handle returns false the iterator stops. Even if handle returns true, values paired to non-nil error are excluded from the returned iterator.
func Sprintf ¶
Sprintf maps seq by fmt.Sprintf
func Sprintf2 ¶
Sprintf2 maps seq by fmt.Sprintf
format receives k as fist and v as second. If callers need reversed order, callers should use %[1]verb and %[2]verb. see https://pkg.go.dev/fmt@go1.23.3#hdr-Explicit_argument_indexes.
