Struct async_fd_lock::RwLockWriteGuard

pub struct RwLockWriteGuard<T: AsOpenFile> { /* private fields */ }

Onwed version of RwLockWriteGuard

Panics

Dropping this type may panic if the lock fails to unlock.

Implementations

impl<T: AsOpenFile> RwLockWriteGuard<T>

pub fn inner(&self) -> &T

pub fn inner_mut(&mut self) -> &mut T

pub fn inner_pin_mut(self: Pin<&mut Self>) -> Pin<&mut T>

pub fn release(self) -> Result<T>

Releases the lock, returning the inner file.

Trait Implementations

impl<T: AsOpenFile + AsyncRead> AsyncRead for RwLockWriteGuard<T>

Delegate AsyncRead to the inner file.

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut ReadBuf<'_>, ) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.

impl<T: AsOpenFile + AsyncWrite> AsyncWrite for RwLockWriteGuard<T>

Delegate AsyncWrite to the inner file.

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Error>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Error>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

impl<T: Debug + AsOpenFile> Debug for RwLockWriteGuard<T>

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

Formats the value using the given formatter.

impl<T: AsOpenFile> Drop for RwLockWriteGuard<T>

fn drop(&mut self)
