import NIOCoreThe core abstractions that make up SwiftNIO.
struct NIOAsyncChannel<Inbound, Outbound> where Inbound : Sendable, Outbound : SendableWraps a NIO Channel object into a form suitable for use in Swift Concurrency.
protocol Channel : AnyObject, ChannelOutboundInvoker, _NIOPreconcurrencySendableA Channel is easiest thought of as a network socket. But it can be anything that is capable of I/O operations such as read, write, connect, and bind.
struct NIOAsyncChannelInboundStream<Inbound> where Inbound : SendableThe inbound message asynchronous sequence of a NIOAsyncChannel.
struct NIOAsyncChannelOutboundWriter<OutboundOut> where OutboundOut : SendableA NIOAsyncChannelOutboundWriter is used to write and flush new outbound messages in a channel.
init(wrappingChannelSynchronously channel: Channel, configuration: Configuration = .init()) throws Initializes a new NIOAsyncChannel wrapping a Channel.
init(wrappingChannelSynchronously channel: Channel, configuration: Configuration = .init()) throws where Outbound == Never Initializes a new NIOAsyncChannel wrapping a Channel where the outbound type is Never.

var inbound: NIOAsyncChannelInboundStream<Inbound> { get }The stream of inbound messages.
var outbound: NIOAsyncChannelOutboundWriter<Outbound> { get }The writer for writing outbound messages.
