A Rust thread-safe, shared (asynchronous) stream buffer designed to lock only on accessing and storing new data.
Streamcatcher is designed to allow seeking on otherwise one-way streams (e.g., command output) whose output needs to be accessed by many threads without constant reallocations, contention over safe read-only data, or unnecessary stalling. Only threads who read in new data ever need to lock the data structure, and do not prevent earlier reads from occurring.
- Lockless access to pre-read data and finished streams.
- Transparent caching of newly read data.
- Allows seeking on read-only bytestreams.
- Piecewise allocation to reduce copying and support unknown input lengths.
- Optional acceleration of reads on stream completion by copying to a single backing store.
- (Stateful) bytestream transformations.
- Async support with the
"async"feature, and runtimes via [
The main algorithm is outlined in this blog post, with rope reference tracking moved to occur only in the core.
