A collection of utilities for working with Data and AsyncSequence.
Lots of stuff here is Foundation-specific. But, the idea is to compliment async-algorithms, not overlap.
dependencies: [
.package(url: "https://github.com/mattmassicotte/Packet", branch: "main")
]FileHandle support:
let fileHandle = FileHandle(...)
for await data in fileHandle.chunks {
// use Data value here
}URLSession support. This offers a considerable performance benefit.
let stream = URLSession.shared.chunks(for: url)
for try await data in stream {
// use Data value here
}Sometimes, to make things work with an existing API, you need to un-chunk a sequence. AsyncByteSequence converts a sequence of Data into a sequence of UInt8. This is inherently less-efficient, but can be a lot less work than changing the consumer.
let bytes = AsyncByteSequence(dataSequence)
for try await byte in bytes {
// one byte at a time
}I'd love to hear from you! Get in touch via mastodon, an issue, or a pull request.
I prefer collaboration, and would love to find ways to work together if you have a similar project.
I prefer indentation with tabs for improved accessibility. But, I'd rather you use the system you want and make a PR than hesitate because of whitespace.
