NIOExtras is a good place for code that is related to NIO but not core. It can also be used to incubate APIs for tasks that are possible with core-NIO but are cumbersome today.
What makes a good contribution to NIOExtras?
- a protocol encoder/decoder pair (also called "codec") that is often used but is small enough so it doesn't need its own repository
- a helper to achieve a task that is harder-than-necessary to achieve with core-NIO
Code Quality / Stability
All code will go through code review like in the other repositories related to the SwiftNIO project.
The policies about breaking API changes in this repository are not as strictly
followed as in the other SwiftNIO repositories. We indicate this by starting
with major version 0 (
0.x.y). We will try to increment the minor version
number whenever there is a breaking change until we release
1.0.0 when we will
start to follow the usual SemVer requirements. We recommend that users depend on
.upToNextMinor as we reserve the right to introduce breaking changes with
minor version increments. For patch level increments, we might only introduce new
dependencies: [ .package(url: "https://github.com/apple/swift-nio-extras.git", .upToNextMinor(from: "0.1.0")), ],
QuiescingHelper: Helps to quiesce a server by notifying user code when all previously open connections have closed.
ByteBuffers on line endings.
ByteBuffers by a fixed number of bytes.
ByteBuffers by a number of bytes specified in a fixed length header contained within the buffer.
LengthFieldPrependerPrepends the number of bytes to outgoing
ByteBuffers as a fixed length header. Can be used in a codec pair with the
RequestResponseHandlerMatches a request and a promise with the corresponding response.
HTTPResponseCompressorCompresses the body of every HTTP/1 response message.
