Struct endbasic_core::program::DemoStoreOverlay

pub struct DemoStoreOverlay<S: Store> { /* fields omitted */ }

Wraps a Store and exposes a bunch of read-only demo files.

All demo file names are case insensitive. However, this preserves the case sensitiveness behavior of the underlying store for any files that are passed through.

This takes ownership of any file names that start with DEMO:, which means any such files in the underlying store become invisible. This should not be a problem in practice because most file systems deny the : character in file names.
