Transparent read only storage trait

Associated Types

type Error

An enumeration of storage errors

Required methods

fn try_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.

fn capacity(&self) -> usize

The capacity of the storage peripheral in bytes.
