pub trait Storage<Data = ()>: AnyStorage + 'static {
    // Required methods
    fn try_read(
        location: GenerationalPointer<Self>
    ) -> Result<Self::Ref<'static, Data>, BorrowError>;
    fn try_write(
        location: GenerationalPointer<Self>
    ) -> Result<Self::Mut<'static, Data>, BorrowMutError>;
    fn set(location: GenerationalPointer<Self>, value: Data);
}

A trait for a storage backing type. (RefCell, RwLock, etc.)

Required Methods

fn try_read( location: GenerationalPointer<Self> ) -> Result<Self::Ref<'static, Data>, BorrowError>

fn try_write( location: GenerationalPointer<Self> ) -> Result<Self::Mut<'static, Data>, BorrowMutError>

Try to write the value. Returns None if the value is no longer valid.

fn set(location: GenerationalPointer<Self>, value: Data)

Set the value if the location is valid
