pub struct Categories { /* private fields */ }Expand description
A (named) object which is used to indicate which categorical data types have the same mapping. The underlying mapping is dynamic, and if gc is true may be automatically cleared when the last reference to it goes away.
Implementations§
Source§impl Categories
impl Categories
Sourcepub fn new(
name: PlSmallStr,
physical: CategoricalPhysical,
gc: bool,
) -> Arc<Categories>
pub fn new( name: PlSmallStr, physical: CategoricalPhysical, gc: bool, ) -> Arc<Categories>
Creates a new Categories object with the given name and physical type.
If gc is true the underlying categories will automatically get cleaned up when the last CategoricalMapping reference goes away, otherwise they are persistent.
Sourcepub fn from_uuid(
name: PlSmallStr,
physical: CategoricalPhysical,
gc: bool,
uuid: Uuid,
) -> Arc<Categories>
pub fn from_uuid( name: PlSmallStr, physical: CategoricalPhysical, gc: bool, uuid: Uuid, ) -> Arc<Categories>
Returns the Categories object with the given UUID. If the UUID is unknown a new one is created.
Sourcepub fn global() -> Arc<Categories>
pub fn global() -> Arc<Categories>
Returns the global Categories.
Sourcepub fn name(&self) -> &PlSmallStr
pub fn name(&self) -> &PlSmallStr
The name of this Categories object (not unique).
Sourcepub fn mapping(&self) -> Arc<CategoricalMapping>
pub fn mapping(&self) -> Arc<CategoricalMapping>
The mapping for this Categories object. If no mapping currently exists it creates a new empty mapping.
pub fn freeze(&self, physical: CategoricalPhysical) -> Arc<FrozenCategories>
