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
