sectorize
A basic library for writing data at an arbitrary address/length to a sectorized medium, like flash memory.
Usage
Here's how I'm using it. This is a snippet from a project I'm working on (and the motivation for writing this crate).
fn write_data(&mut self, start_addr: usize, buf: &[u8]) {
for s in SectorizeIter::new(SECTOR_SIZE, start_addr, buf.len()) {
let mut existing = self.read_slice(s.sector_index * SECTOR_SIZE);
// only write if there's a difference
if existing[s.sector_start..s.sector_end] != buf[s.input_start..s.input_end] {
existing[s.sector_start..s.sector_end]
.copy_from_slice(&buf[s.input_start..s.input_end]);
self.write_sector(s.sector_index * SECTOR_SIZE, &existing);
}
}
}
