}

A registry that tracks serialized shared memory.

This trait is required to serialize shared pointers.

Required Methods

fn get_shared_ptr(&self, value: *const u8) -> Option<usize>

Gets the position of a previously-added shared pointer.

Returns None if the pointer has not yet been added.

fn add_shared_ptr( &mut self, value: *const u8, pos: usize, ) -> Result<(), Self::Error>

Adds the position of a shared pointer to the registry.

Provided Methods

fn get_shared<T: ?Sized>(&self, value: &T) -> Option<usize>

Gets the position of a previously-added shared value.

Returns None if the value has not yet been added.

fn add_shared<T: ?Sized>( &mut self, value: &T, pos: usize, ) -> Result<(), Self::Error>

Adds the position of a shared value to the registry.

fn serialize_shared<T: SerializeUnsized<Self> + ?Sized>( &mut self, value: &T, ) -> Result<usize, Self::Error>

where Self: Serializer,

Archives the given shared value and returns its position. If the value has already been added then it returns the position of the previously added value.

Object Safety

This trait is not object safe.
