# 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`.

## TODO

* NoFlash backend
* read_int()
* write_str()
* automatic value coercion
* support for floats

### Ideas

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