Functions

func CopyAttrsFromUnixToFuse

func CopyAttrsFromUnixToFuse(st *unix.Stat_t, out *fuse.Attr)

func ToStatus

func ToStatus(err error) fuse.Status

Types

type LoopbackFileSystem

type LoopbackFileSystem struct {
	RootDir  string
	RootFD   int
	OnAccess func(path string)
	OnRead   func(path string)
	// contains filtered or unexported fields
}

func NewLoopbackFileSystem

func NewLoopbackFileSystem(root string) (*LoopbackFileSystem, error)

Based on the hanwen/go-fuse loopback example, but wth "openat" everywhere (because we want to mount /a over /a in prod) - otherwise if you went by path instead of by fd, accessing /a would then request /a and cause an infinite loop.

func (*LoopbackFileSystem) AllowReads

func (fs *LoopbackFileSystem) AllowReads()

func (*LoopbackFileSystem) Root
