Trait smolapps::tftp::Context

pub trait Context {
    type Handle: Handle;
    fn open(
        &mut self, 
        filename: &str, 
        write_mode: bool
    ) -> Result<Self::Handle, ()>;
    fn close(&mut self, handle: Self::Handle);
}

The context over which the Server will operate.

The context allows the Server to open and close Handles to files. It does not impose any restriction on the context hierarchy: it could be a flat structure or implement a directory tree. It is up to the implementors to define, if required, the concepts of path separators and nesting levels.
