pub struct FerroPropertyRegistry { /* private fields */ }

Tracks registered property definitions.

Implementations

impl FerroPropertyRegistry

pub fn instance() -> &'static FerroPropertyRegistry

The property registry of the current thread.

pub fn unregister_by_module( &self, types: impl IntoIterator<Item = &'static TypeInfo>, ) -> bool

Unregisters the properties of the given types: removes the metadata every registered, attached and direct property holds for each type, and the property lists cached for it.

Returns whether the types were unregistered. (The managed original returns false when unregistering throws; nothing fails here.)

pub fn get_registered( &self, type_: &'static TypeInfo, ) -> Rc<Vec<&'static FerroProperty>>

Gets all non-attached properties registered on a type (and its bases).

pub fn get_registered_attached( &self, type_: &'static TypeInfo, ) -> Rc<Vec<&'static FerroProperty>>

Gets all attached properties registered on a type (and its bases).

pub fn get_registered_direct( &self, type_: &'static TypeInfo, ) -> Rc<Vec<&'static FerroProperty>>

Gets all direct properties registered on a type (and its bases).

pub fn get_registered_inherited( &self, type_: &'static TypeInfo, ) -> Rc<Vec<&'static FerroProperty>>

Gets all inherited properties registered on a type: registered and attached properties whose values are inherited.

pub fn get_declared( &self, type_: &'static TypeInfo, ) -> Vec<&'static FerroProperty>

Gets the properties a type itself declares (registered with the type as owner: styled, direct, attached and added-owner properties), in declaration order, without those of its base types.

pub fn get_registered_for( &self, o: &FerroObject, ) -> Rc<Vec<&'static FerroProperty>>

Gets all properties registered on an object’s type.

pub fn get_registered_direct_for<T: PropertyValue>( &self, o: &FerroObject, property: &'static DirectPropertyBase<T>, ) -> &'static DirectPropertyBase<T>

Finds the direct property registered on the type of o that shares the identity of property.

Panics if the property is not registered on the object’s type.

pub fn find_registered_direct<T: PropertyValue>( &self, o: &FerroObject, property: &'static DirectPropertyBase<T>, ) -> Option<&'static DirectPropertyBase<T>>

Finds the direct property registered on the type of o that shares the identity of property.

pub fn find_registered( &self, type_: &'static TypeInfo, name: &str, ) -> Option<&'static FerroProperty>

Finds a registered property on a type by name.

Panics if name contains a .: attached properties are not looked up through this method.

pub fn find_registered_for( &self, o: &FerroObject, name: &str, ) -> Option<&'static FerroProperty>

Finds a registered property on an object’s type by name.

pub fn find_registered_by_id(&self, id: u32) -> Option<&'static FerroProperty>

Finds a registered property by its ID.

pub fn is_registered( &self, type_: &'static TypeInfo, property: &FerroProperty, ) -> bool

Checks whether a property is registered on a type (or its bases).

pub fn is_registered_for( &self, o: &FerroObject, property: &FerroProperty, ) -> bool

Checks whether a property is registered on an object’s type.

pub fn register<P: Registrable>( &self, type_: &'static TypeInfo, property: &'static P, )

Registers a property on a type.

You won’t usually want to call this method directly; use the FerroProperty::register* functions instead.

pub fn register_attached<P: Registrable>( &self, type_: &'static TypeInfo, property: &'static P, )

Registers an attached property on a host type.

Trait Implementations

impl Default for FerroPropertyRegistry

fn default() -> Self
