sourcefn read(&mut self, offset: u32, bytes: &mut [u8]) -> Result<(), Self::Error>
fn read(&mut self, offset: u32, bytes: &mut [u8]) -> Result<(), Self::Error>
Read a slice of data from the storage peripheral, starting the read
operation at the given address offset, and reading bytes.len()
bytes.
This should throw an error in case bytes.len()
will be larger than
self.capacity() - offset
.
