QGIS Algorithm provided by QGIS (native c++) Buffer (native:buffer). This algorithm computes a buffer area for all the features in an input layer, using a fixed or dynamic distance. The segments parameter controls the number of line segments to use to approximate a quarter circle when creating rounded offsets. The end cap style parameter controls how line endings are handled in the buffer. The join style parameter specifies whether round, miter or beveled joins should be used when offsetting corners in a line. The miter limit parameter is only applicable for miter join styles, and controls the maximum distance from the offset curve to use when creating a mitered join. —————- Notes —————- - This algorithm may drop existing primary keys or FID values and regenerate them in output layers, depending on the input parameters.

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.
