Struct polyfuse::Session

pub struct Session { /* fields omitted */ }

FUSE session driver.

Methods

impl Session

pub fn connection_info(&self) -> &ConnectionInfo

Returns the information about the FUSE connection.

pub fn buffer_size(&self) -> usize

Returns the buffer size required to receive one request.

pub async fn process<'_, '_, '_, F: ?Sized, T: ?Sized>(
    &'_ self,
    fs: &'_ F,
    io: &'_ mut T
) -> Result<()> where
    F: Filesystem,
    T: Reader + Writer + Send + Unpin, 

Process an incoming request using the specified filesystem operations.

pub async fn notify_inval_inode<'_, '_, W: ?Sized>(
    &'_ self,
    writer: &'_ mut W,
    ino: u64,
    off: i64,
    len: i64
) -> Result<()> where
    W: Writer + Unpin, 

Notify the cache invalidation about an inode to the kernel.

pub async fn notify_inval_entry<'_, '_, W: ?Sized>(
    &'_ self,
    writer: &'_ mut W,
    parent: u64,
    name: impl AsRef<OsStr>
) -> Result<()> where
    W: Writer + Unpin, 

Notify the invalidation about a directory entry to the kernel.

pub async fn notify_delete<'_, '_, W: ?Sized>(
    &'_ self,
    writer: &'_ mut W,
    parent: u64,
    child: u64,
    name: impl AsRef<OsStr>
) -> Result<()> where
    W: Writer + Unpin, 

Notify the invalidation about a directory entry to the kernel.

The role of this notification is similar to notify_inval_entry. Additionally, when the provided child inode matches the inode in the dentry cache, the inotify will inform the deletion to watchers if exists.

pub async fn notify_store<'_, '_, '_, '_, W: ?Sized>(
    &'_ self,
    writer: &'_ mut W,
    ino: u64,
    offset: u64,
    data: &'_ [&'_ [u8]]
) -> Result<()> where
    W: Writer + Unpin, 

Push the data in an inode for updating the kernel cache.

pub async fn notify_retrieve<'_, '_, W: ?Sized>(
    &'_ self,
    writer: &'_ mut W,
    ino: u64,
    offset: u64,
    size: u32
) -> Result<u64> where
    W: Writer + Unpin, 

Retrieve data in an inode from the kernel cache.

pub async fn notify_poll_wakeup<'_, '_, W: ?Sized>(
    &'_ self,
    writer: &'_ mut W,
    kh: u64
) -> Result<()> where
    W: Writer + Unpin, 

Send I/O readiness to the kernel.

Trait Implementations

impl Debug for Session

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

Formats the value using the given formatter.
