QGIS Algorithm provided by QGIS (native c++) Single sided buffer (native:singlesidedbuffer). This algorithm buffers lines by a specified distance on one side of the line only. The segments parameter controls the number of line segments to use to approximate a quarter circle when creating rounded buffers. The join style parameter specifies whether round, miter or beveled joins should be used when buffering corners in a line. The miter limit parameter is only applicable for miter join styles, and controls the maximum distance from the buffer to use when creating a mitered join.

)source - Input layer. Path to a vector layer.
distance - Distance. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
enum of ("Left", "Right") - Side. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Segments. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
enum of ("Round", "Miter", "Bevel") - Join style. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Miter limit. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
sink - Buffered. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
