Trait Pooling

pub trait Pooling<E = <Self as Fallible>::Error> {
    // Required methods
    fn start_pooling(&mut self, address: usize) -> PoolingState;
    unsafe fn finish_pooling(
        &mut self,
        address: usize,
        ptr: ErasedPtr,
        drop: unsafe fn(ErasedPtr),
    ) -> Result<(), E>;
}

A shared pointer deserialization strategy.

This trait is required to deserialize Rc and Arc.

Required Methods

fn start_pooling(&mut self, address: usize) -> PoolingState

Starts pooling the value associated with the given address.

unsafe fn finish_pooling( &mut self, address: usize, ptr: ErasedPtr, drop: unsafe fn(ErasedPtr), ) -> Result<(), E>

Finishes pooling the value associated with the given address.

Returns an error if the given address was not pending.

Safety

The given drop function must be valid to call with ptr.
