Trait nuts_backend::HeaderSet

pub trait HeaderSet<B: Backend> {
    // Required method
    fn put_header_bytes(&mut self, bytes: &[u8; 512]) -> Result<(), B::Err>;
}

Trait used to update the header of a container.

The container uses the HeaderSet::put_header_bytes() method to ask the backend to put the given bytes into the header. The container does not know where the backend stores the header, that’s why such a trait is used. Not more than HEADER_MAX_SIZE bytes can be stored in the header.
