Struct ShareableBuffer

pub struct ShareableBuffer { /* private fields */ }

An in memory buffer that allows for shared ownership and interior mutability. The underlying buffer is wrapped in an Arc and RwLock, so cloning the instance allows multiple owners to have access to the same underlying buffer.

Implementations

impl ShareableBuffer

pub fn into_inner(self) -> Option<Vec<u8>>

Consumes this instance and returns the underlying buffer. Returns None if there are other references to the instance.

pub fn to_vec(&self) -> Vec<u8>

Returns a clone of the the underlying buffer as a Vec.

pub fn len(&self) -> usize

Returns the number of bytes in the underlying buffer.

pub fn is_empty(&self) -> bool

Returns true if the underlying buffer is empty.

pub fn from_bytes(bytes: &[u8]) -> Self

Creates a new instance with buffer initialized from the underylying bytes.

Trait Implementations

impl Clone for ShareableBuffer

fn clone(&self) -> ShareableBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShareableBuffer

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

Formats the value using the given formatter.

impl Default for ShareableBuffer

fn default() -> ShareableBuffer

Returns the “default value” for a type.

impl Write for ShareableBuffer

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, fmt: 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.
