protocol SerialExecutor : ExecutorSupertypes
protocol ExecutorA service that can execute jobs.
protocol SendableA type whose values can safely be passed across concurrency domains by copying.
Requirements
func asUnownedSerialExecutor() -> UnownedSerialExecutor Convert this executor value to the optimized form of borrowed executor references.
func enqueue(consuming ExecutorJob) func isSameExclusiveExecutionContext(other: Self) -> Bool If this executor has complex equality semantics, and the runtime needs to compare two executors, it will first attempt the usual pointer-based equality check, and if it fails it will compare the types of both executors, if they are the same, it will finally invoke this method, in an attempt to let the executor itself decide if this and the
otherexecutor represent the same serial, exclusive, isolation context.func enqueue(consuming Job) func enqueue(UnownedJob)

Members
func assertIsolated(() -> String, file: StaticString, line: UInt) Performs an executor check in debug builds.
func preconditionIsolated(() -> String, file: StaticString, line: UInt) Unconditionally if the current task is executing on the expected serial executor, and if not crash the program offering information about the executor mismatch.
Extension in NIOCore
Subtypes
protocol NIOSerialEventLoopExecutorA helper protocol that can be mixed in to a NIO
EventLoopto provide an automatic conformance toSerialExecutor.
