Struct DFUuid 

pub struct DFUuid(/* private fields */);

Defines the extension type logic for the canonical arrow.uuid extension type. This extension type defines that a field should be interpreted as a UUID.

See DFExtensionType for information on DataFusion’s extension type mechanism. See also Uuid for the implementation of arrow-rs, which this type uses internally.
