Trait Implementations

impl<'a, T: ExtWrite<'a> + Clone> Clone for FlushLockWrite<'a, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T: Debug + ExtWrite<'a>> Debug for FlushLockWrite<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: ExtWrite<'a>> ExtWrite<'a> for FlushLockWrite<'a, T>

type LockWrite = FlushDropWrite<<T as ExtWrite<'a>>::LockWrite>

fn lock(&'a self) -> Self::LockWrite

Blocking the output stream.

fn lock_fn<F: FnMut(Self::LockWrite) -> R, R>(&'a self, f: F) -> R

Alternative method of blocking the output stream using the closure.

impl<'a, T: ExtWrite<'a>> From<T> for FlushLockWrite<'a, T>

fn from(a: T) -> Self

Converts to this type from the input type.

impl<'a, T: ExtWrite<'a>> Write for FlushLockWrite<'a, T>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<()>

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<()>

Writes a formatted string into this writer, returning any error encountered.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

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

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
