Flags which control how QgsProviderUtils::sublayerDetailsAreIncomplete() tests for completeness.

Returns true
if the sublayer details are incomplete, and require a more in-depth scan.
For instance, if the details contain any vector sublayers with unknown geometry types then a query with the Qgis::SublayerQueryFlag::ResolveGeometryType flag is required.
The flags argument can be used to control the level of completeness required during the test.

Suggests a suitable layer name given only a file path.
Usually this corresponds to the base file name of path (e.g. "rivers" for a path of "c:/my data/water/rivers.shp"). However some data formats which use fixed file paths (such as aigrid files) will instead return the parent directory name (e.g. "rivers" for a path of "c:/my data/water/rivers/hdr.adf").
