Trait NonvolatileStorage 

pub trait NonvolatileStorage<'a> {
    // Required methods
    fn set_client(&self, client: &'a dyn NonvolatileStorageClient);
    fn read(
        &self,
        buffer: &'static mut [u8],
        address: usize,
        length: usize,
    ) -> Result<(), (ErrorCode, &'static mut [u8])>;
    fn write(
        &self,
        buffer: &'static mut [u8],
        address: usize,
        length: usize,
    ) -> Result<(), (ErrorCode, &'static mut [u8])>;
}

Simple interface for reading and writing nonvolatile memory. It is expected that drivers for nonvolatile memory would implement this trait.

Required Methods

fn set_client(&self, client: &'a dyn NonvolatileStorageClient)

fn read( &self, buffer: &'static mut [u8], address: usize, length: usize, ) -> Result<(), (ErrorCode, &'static mut [u8])>

Read length bytes starting at address address in to the provided buffer. The buffer must be at least length bytes long. The address must be in the address space of the physical storage.

On error, the buffer is returned alongside the ErrorCode so the caller does not lose ownership of it.

fn write( &self, buffer: &'static mut [u8], address: usize, length: usize, ) -> Result<(), (ErrorCode, &'static mut [u8])>

Write length bytes starting at address address from the provided buffer. The buffer must be at least length bytes long. This address must be in the address space of the physical storage.

On error, the buffer is returned alongside the ErrorCode so the caller does not lose ownership of it.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
