Mean and lean components for working with ultralight **persistent data channels** in rust. Channels could be used for communication, transaction journaling, live replication of an application state or as a backend for persisting software system images.
## Basic Concepts
#### Persistent data channels
* A mechanism to sequentially persist data at a very fast rate
* They are **writer bound** - it is a writer which creates them and specify the particular structure of a channel such size, maximum record length, or timeout
* They have a fixed predefined capacity.
* Once a channel is closed, is full, or is abandoned it will never be used again for writing.
* They are byte-oriented sinks.
* They are backed by a file; using a RAM disk for storage such as tempfs or /dev/shm could provide blazing fast speeds.
* They always use little endian byte order.
#### Writers and Readers
* Writers are components which push data into a persistent channel. For each channel there is only one writer.
* Write operation can be done in stages using a chain of handlers.
* Readers are components which poll data from a channel. Data available in the channel could be consumed multiple times, sequential or in parallel by multiple readers.
* The default implementations for both readers and writers are non-blocking.
* Readers also offer a straight `Iterator` API.
## Usage
Add this to your `Cargo.toml`:
```toml
[dependencies]
kekbit = "0.3.333"
```
See the [Examples](https://github.com/motoras/kekbit/blob/master/examples/README.md) for detailed usage.
## Compatibility
The minimum supported Rust version is 1.31. Any change to this is considered a breaking change.
