Struct SharedBuffer

pub struct SharedBuffer {
    pub buffer: Arc<Mutex<Vec<u8>>>,
}

A buffer with interior mutability shared by the SerializedFileWriter and ObjectStore writer

Fields

buffer: Arc<Mutex<Vec<u8>>>

The inner buffer for reading and writing

The lock is used to obtain internal mutability, so no worry about the lock contention.

Implementations

impl SharedBuffer

pub fn new(capacity: usize) -> Self

Trait Implementations

impl Clone for SharedBuffer

fn clone(&self) -> SharedBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Write for SharedBuffer

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_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(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

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 write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

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

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

where Self: Sized,

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