Introduction

orderwal is generic-purpose, atomic, ordered, zero-copy read, zero-cost (in-place) write, concurrent-safe, pre-allocate style (memory map) write-ahead-log for developing databases.

orderwal also supports generic structured key and value types, which is not limited to just bytes like other implementations.

Installation

Default (with on-disk support)
```
[dependencies]
orderwal = "0.5"
```

std only (without on-disk support)

[dependencies]
orderwal = { version = "0.5", default-features = false, features = ["std"] }

no-std (alloc required)

[dependencies]
orderwal = { version = "0.5", default-features = false, features = ["alloc"] }

Example

See examples for more information.
