Module: RFuse::Adapter

Defined in:
lib/rfuse/rfuse.rb

Overview

Map callback methods to be compatible for legacy RFuse

All native FuseOperations callback signatures are amended to take FuseContext as the first argument.

A subset of callbacks are documented here where their signatures are further altered to match RFuse

RFuse did not support Fuse3 adapter module
