Struct InMemoryEditor 

pub struct InMemoryEditor { /* private fields */ }

Mutable v1 file facade implemented by loading frames and rewriting the file on save.

FWOB v1 stores frames as a flat sorted array. Deletes require compaction in the original C# implementation; this editor performs the same logical operation by rewriting the file. That is acceptable for compatibility and for the rare bulk-deletion workflow that v2 is designed around.
