Struct kv::ValueMut

pub struct ValueMut<'a>(_);

A mutable reference to an existing value slice

Methods

impl<'a> ValueMut<'a>

Important traits for ValueMut<'a>

impl<'a> Write for ValueMut<'a>

pub fn new(buf: &'a mut [u8]) -> ValueMut<'a>

Create a new ValueMut from an existing byte slice

pub fn as_value<V: Value<'a>>(&'a self) -> ValueRef<'a>

Convert a ValueMut to ValueRef

Trait Implementations

impl<'a> AsMut<[u8]> for ValueMut<'a>

fn as_mut(&mut self) -> &mut [u8]

Performs the conversion.

impl<'a> AsRef<[u8]> for ValueMut<'a>

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl<'a> Debug for ValueMut<'a>

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

Formats the value using the given formatter.

impl<'a> Write for ValueMut<'a>

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

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

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

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

Attempts to write an entire buffer 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

Creates a "by reference" adaptor for this instance of Write.
