Struct PartialWritableKeyPath 

pub struct PartialWritableKeyPath<Root> { /* private fields */ }

PartialWritableKeyPath - Hides the Value type but keeps Root visible (writable)

Why PhantomData?

See PartialKeyPath documentation for explanation of why PhantomData is needed.

Implementations

impl<Root> PartialWritableKeyPath<Root>

pub fn new<Value>( keypath: WritableKeyPath<Root, Value, impl for<'r> Fn(&'r mut Root) -> &'r mut Value + 'static>, ) -> PartialWritableKeyPath<Root>

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

pub fn from<Value>( keypath: WritableKeyPath<Root, Value, impl for<'r> Fn(&'r mut Root) -> &'r mut Value + 'static>, ) -> PartialWritableKeyPath<Root>

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

Create a PartialWritableKeyPath from a concrete WritableKeyPath Alias for new() for consistency with from() pattern

pub fn get_mut<'r>(&self, root: &'r mut Root) -> &'r mut (dyn Any + 'static)

pub fn value_type_id(&self) -> TypeId

Get the TypeId of the Value type

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

where Value: Any,

Try to downcast the result to a specific type

Trait Implementations

impl<Root> Clone for PartialWritableKeyPath<Root>

where Root: Clone,

fn clone(&self) -> PartialWritableKeyPath<Root>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
