ffuse: FUSE driver for FFS

This module defines a FUSE filesystem that exposes the FFS data format.

Note: The ffuse tool that used to live here has been susperseded by the mount subcommand of the ffs tool.

Overview

Package ffuse implements a FUSE filesystem driver backed by the flexible filesystem package (github.com/creachadair/ffs). It is compatible with the github.com/hanwen/go-fuse packages for FUSE integration.

Types

type FS

type FS struct {
	// The fs.Inode is self-synchronizing, and is accessed via its
	// impelmentation of the fs.InodeEmbedder interface. Its key requirement is
	// that we must not copy the value.
	fs.Inode
	// contains filtered or unexported fields
}
