Returns if the ChannelHandler of the given type is contained in the pipeline.
@preconcurrency func containsHandler<Handler>(type: Handler.Type) -> EventLoopFuture<Void> where Handler : ChannelHandler s7NIOCore15ChannelPipelineC15containsHandler4typeAA15EventLoopFutureCyytGxm_tAA0bE0RzlF What are these?162LMThe type of the handler.
An EventLoopFuture that is succeeded if a handler of the given type is contained in the pipeline. Otherwise the future will be failed with an error.
import NIOCoreThe core abstractions that make up SwiftNIO.
final class ChannelPipelineA list of ChannelHandlers that handle or intercept inbound events and outbound operations of a Channel. ChannelPipeline implements an advanced form of the Intercepting Filter pattern to give a user full control over how an event is handled and how the ChannelHandlers in a pipeline interact with each other.
protocol ChannelHandler : AnyObjectBase protocol for handlers that handle I/O events or intercept an I/O operation.
final class EventLoopFuture<Value>Holder for a result that will be provided later.
typealias Void = ()The return type of functions that don’t explicitly specify a return type, that is, an empty tuple ().
init(channel: any Channel) Create ChannelPipeline for a given Channel. This method should never be called by the end-user directly: it is only intended for use with custom Channel implementations. Users should always use channel.pipeline to access the ChannelPipeline for a Channel.
var debugDescription: String { get }let eventLoop: any EventLoopThe EventLoop that is used by the underlying Channel.
var syncOperations: ChannelPipeline.SynchronousOperations { get }Returns a view of operations which can be performed synchronously on this pipeline. All operations must be called on the event loop.
