type Filesystem

type Filesystem struct {
	// contains filtered or unexported fields
}

Filesystem is a facade for all fs-related functionality.

func NewFilesystem

func NewFilesystem(lp *loop.Loop, opts ...FilesystemOption) *Filesystem

NewFilesystem returns facade for interacting with uring-based filesystem functionality.

func (*Filesystem) Open

func (fsm *Filesystem) Open(name string, flags int, mode os.FileMode) (*File, error)

Open a file.

type FilesystemOption

type FilesystemOption func(*Filesystem)

FilesystemOption ...

func RegisterFiles

func RegisterFiles(n int) FilesystemOption

RegisterFiles enables file registration in uring when file is opened. n is a hint to for fds slice allocation. When fds slice needs to grow registration module will have to perform two unixs (unregister files, register files).

type Write

type Write struct {
	Buf    []byte
	Offset uint64
}
