# Simple Flash Key Value store
Tries to keep flash wear low by continuously appending data,
automatically erasing and rewriting when full.
## Store requirements
* Reading must be possible by memory-mapping a `&[u8]` slice
* Must support `erase()` for compaction,
* Writing must support `program()` with an offset and `&[u8]` payload
For details see `trait StoreBackend`.

## Ideas

* iterator (quadratic)
* compaction to a second backend instead on stack
* StoreBackend-configurable erased data detection
