Functions ¶
func WrapXd3SeekGoStream ¶
func Xd3Decode ¶
Performs delta decoding using xdelta3, reconstructing the target data from a base and a delta and writing it to the output via the provided writer. It leverages the C xd3_decode function, passing Go io.Reader and io.Writer via CGO handles.
Parameters:
- base: io.Reader for the source (base) data.
- delta: io.Reader for the delta data.
- target: io.Writer for the resulting target data.
Returns nil on success, otherwise an error.
func Xd3Encode ¶
Performs delta encoding using xdelta3, creating a delta from a base to a target data and writing it to the output via the provided writer. It leverages the C xd3_encode function, passing Go io.Reader and io.Writer via CGO handles.
Parameters:
- base: io.Reader for the source (base) data.
- target: io.Reader for the target data.
- delta: io.Writer for the resulting delta data.
Returns nil on success, otherwise an error
