pub struct TypeRegistry {
registry: HashMap<String, LazyDatatype>,
}Expand description
Computes and maintains a registry of DataTypes for specified flatbuffers
definitions.
Fields§
§registry: HashMap<String, LazyDatatype>Implementations§
Source§impl TypeRegistry
impl TypeRegistry
Sourcepub fn register(&mut self, obj: &mut Object)
pub fn register(&mut self, obj: &mut Object)
Computes the Arrow datatype for the specified object and stores it in the registry, to be resolved later on.
Sourcepub fn try_get(&self, fqname: impl AsRef<str>) -> Option<DataType>
pub fn try_get(&self, fqname: impl AsRef<str>) -> Option<DataType>
Retrieves the DataType associated with the given fully-qualified
name, if any.
This does type resolution just-in-time.
Sourcepub fn get(&self, fqname: impl AsRef<str>) -> DataType
pub fn get(&self, fqname: impl AsRef<str>) -> DataType
Retrieves the DataType associated with the given fully-qualified
name.
Panics if missing.
This does type resolution just-in-time.

§fn into_any(self: Box<T>) -> Box<dyn Any>
fn into_any(self: Box<T>) -> Box<dyn Any>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.§impl<T> DowncastSync for T
