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.

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"] }
