Struct AnyKeyPath 

pub struct AnyKeyPath { /* private fields */ }

AnyKeyPath - Hides both Root and Value types Equivalent to Swift’s AnyKeyPath Useful for storing keypaths in collections without knowing either type

Why No PhantomData?

Unlike PartialKeyPath, AnyKeyPath doesn’t need PhantomData because:

• Both Root and Value types are completely erased
• We store TypeId instead for runtime type checking
• The type information is encoded in the closure’s behavior, not the struct
• There’s no generic type parameter to track at compile time

Implementations

impl AnyKeyPath

pub fn new<Root, Value>( keypath: OptionalKeyPath<Root, Value, impl for<'r> Fn(&'r Root) -> Option<&'r Value> + 'static>, ) -> Self

where Root: Any + 'static, Value: Any + 'static,

pub fn from<Root, Value>( keypath: OptionalKeyPath<Root, Value, impl for<'r> Fn(&'r Root) -> Option<&'r Value> + 'static>, ) -> Self

where Root: Any + 'static, Value: Any + 'static,

Create an AnyKeyPath from a concrete OptionalKeyPath Alias for new() for consistency with from() pattern

pub fn get<'r>(&self, root: &'r dyn Any) -> Option<&'r dyn Any>

pub fn root_type_id(&self) -> TypeId

Get the TypeId of the Root type

pub fn value_type_id(&self) -> TypeId

Get the TypeId of the Value type

pub fn get_as<'a, Root: Any, Value: Any>( &self, root: &'a Root, ) -> Option<Option<&'a Value>>

Try to get the value with type checking

Trait Implementations

impl Clone for AnyKeyPath

fn clone(&self) -> AnyKeyPath

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
