The session data structure

Fields

filesystem: FS

Filesystem operation implementations

proto_major: u32

FUSE protocol major version

proto_minor: u32

FUSE protocol minor version

initialized: bool

True if the filesystem is initialized (init operation done)

destroyed: bool

True if the filesystem was destroyed (destroy operation done)

splice_write: bool

True, if splice() syscall should be used for /dev/fuse

max_background: u16

Number of queued requests in the kernel

congestion_threshold: u16

Threshold when waiting fuse users are put into sleep state instead of busy loop

Methods

impl<FS: Filesystem> Session<FS>

pub fn new_from_fd(
    filesystem: FS,
    fd: RawFd,
    mountpoint: &Path,
    splice_write: bool,
    max_background: u16,
    congestion_threshold: u16
) -> Result<Session<FS>>

Create a new session by using a file descriptor "/dev/fuse"

pub fn mountpoint(&self) -> &Path

Return path of the mounted filesystem

pub fn run(&mut self) -> Result<()>

Run the session loop that receives kernel requests and dispatches them to method calls into the filesystem. This read-dispatch-loop is non-concurrent to prevent having multiple buffers (which take up much memory), but the filesystem methods may run concurrent by spawning threads.

impl<'a, FS: Filesystem + Send + 'a> Session<FS>

pub unsafe fn spawn(self) -> Result<BackgroundSession<'a>>

Run the session loop in a background thread

Trait Implementations

impl<FS: Debug + Filesystem> Debug for Session<FS>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<FS: Filesystem> Drop for Session<FS>

fn drop(&mut self)

Executes the destructor for this type.
