Struct InMemorySys

Source 
pub struct InMemorySys(/* private fields */);
Expand description

An in-memory system implementation useful for testing.

This is extremely untested and sloppily implemented. Use with extreme caution and only for testing. You will encounter bugs. Please submit fixes. I implemented this lazily and quickly.
