Expand description

A trait for data stored within an Epoll instance.

Associated Types

The type of an element owned by this context.

The type of a value used to refer to an element owned by this context.

Required methods

Assume ownership of data, and returning a Target.

Encode target as a u64. The only requirement on this value is that it be decodable by decode.

Decode raw, which is a value encoded by encode, into a Target.

Safety

raw must be a u64 value returned from encode, from the same context, and within the context’s lifetime.

Release ownership of the value referred to by target and return it.
