Interface for accessing a runtime specific memory.

Required Methods

fn read<'instance>( &self, instance: &'instance Instance, location: GuestPointer, length: u32, ) -> Result<Cow<'instance, [u8]>, RuntimeError>

Reads length bytes from memory from the provided location.

fn write( &mut self, instance: &mut Instance, location: GuestPointer, bytes: &[u8], ) -> Result<(), RuntimeError>

Writes the bytes to memory at the provided location.
