BackPressureHandler
ChannelHandler implementation which enforces back-pressure by stopping to read from the remote peer when it cannot write back fast enough. It will start reading again once pending data was written.
final class BackPressureHandlerChannelHandler implementation which enforces back-pressure by stopping to read from the remote peer when it cannot write back fast enough. It will start reading again once pending data was written.
final class BackPressureHandlerimport NIOCoreThe core abstractions that make up SwiftNIO.
final class AcceptBackoffHandlerA ChannelHandler that implements a backoff for a ServerChannel when accept produces an IOError. These errors are often recoverable by reducing the rate at which we call accept.
final class NIOCloseOnErrorHandlerA ChannelInboundHandler that closes the channel when an error is caught
final class IdleStateHandlerTriggers an IdleStateEvent when a Channel has not performed read, write, or both operation for a while.
protocol ChannelHandler : AnyObjectBase protocol for handlers that handle I/O events or intercept an I/O operation.
protocol ChannelInboundHandler : _ChannelInboundHandler, _EmittingChannelHandlerChannelHandler which handles inbound I/O events for a Channel.
protocol ChannelOutboundHandler : _ChannelOutboundHandler, _EmittingChannelHandlerChannelHandler which handles outbound I/O events or intercept an outbound I/O operation for a Channel.
protocol RemovableChannelHandler : ChannelHandlerA RemovableChannelHandler is a ChannelHandler that can be dynamically removed from a ChannelPipeline whilst the Channel is operating normally. A RemovableChannelHandler is required to remove itself from the ChannelPipeline (using ChannelHandlerContext.leavePipeline) as soon as possible.
protocol _ChannelInboundHandler : ChannelHandlerUntyped ChannelHandler which handles inbound I/O events.
protocol _ChannelOutboundHandler : ChannelHandlerUntyped ChannelHandler which handles outbound I/O events or intercept an outbound I/O operation.
protocol _EmittingChannelHandlerChannelHandler which will emit data by calling ChannelHandlerContext.write.

func register(context: ChannelHandlerContext, promise: EventLoopPromise<Void>?) func removeHandler(context: ChannelHandlerContext, removalToken: ChannelHandlerContext.RemovalToken) Implements the default behaviour which is to synchronously remove the handler from the pipeline. Thanks to this, stateless ChannelHandlers can just use RemovableChannelHandler as a marker-protocol and declare themselves as removable without writing any extra code.
