go_channels 0.1.1

go_channels: ^0.1.1 copied to clipboard

First pub.dev release. The package was developed under the name channels, which pub.dev rejects as too similar to the existing channel package, so it is published as go_channels. The import is package:go_channels/go_channels.dart; the API is unchanged.

• Add a diagram to the README, and declare it as a pub.dev screenshot, showing the one thing that separates an unbuffered channel from a buffered one: when send completes. Unbuffered rendezvous — send finishes at the receive; buffered lets send return while the buffer has room, and blocks only when it is full.

• Initial release.
• Channel<T>: buffered and unbuffered channels with send, receive, receiveOr (Go-style value, ok), a stream view, and close.
• select: waits on several channel receives/sends at once and runs exactly one, with onDefault (non-blocking) and onTimeout branches; random choice among ready branches for fairness.
• Structured concurrency: withTaskScope and waitAll run a group of tasks fail-fast, CancelToken provides cooperative cancellation, and withTimeout cancels on a deadline.
