Enumeration representing the different types of cancellation that may be requested from or implemented by an asynchronous operation.
enum class cancellation_type : unsigned int
Bitmask representing no types of cancellation.
Requests cancellation where, following a successful cancellation, the only safe operations on the I/O object are closure or destruction.
Requests cancellation where a successful cancellation may result in partial side effects or no side effects. Following cancellation, the I/O object is in a well-known state, and may be used for further operations.
Requests cancellation where a successful cancellation results in no apparent side effects. Following cancellation, the I/O object is in the same observable state as it was prior to the operation.
Bitmask representing all types of cancellation.
