Expand description

A registry that tracks serialized shared memory.

This trait is required to serialize shared pointers.

Required Methods§

source

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.

source

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§

source

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.

source

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

Adds the position of a shared value to the registry.

source

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.
