Implementations

impl BufWrite

pub fn new_no_lock(size: usize) -> BufWrite

Construct a new BufWrite that is NOT mem_locked.

pub fn new_mem_locked(size: usize) -> Result<BufWrite, OneErr>

Construct a new BufWrite that IS mem_locked. Use this for passwords / private keys, etc, but NOT everything, locked memory is a finite resource.

pub fn deep_clone_no_lock<O>(o: O) -> BufWrite where
O: 'static + Into<BufRead> + Send,

Deep clone the data referred to by another buffer object, into a new non-memory-locked BufWrite instance.

pub fn deep_clone_mem_locked<O>(o: O) -> Result<BufWrite, OneErr> where
O: 'static + Into<BufRead> + Send,

Deep clone the data referred to by another buffer object, into a new MEMORY LOCKED BufWrite instance.

pub fn len(&self) -> usize

The length of this buffer.

pub fn is_empty(&self) -> bool

Is this buffer empty?

pub fn read_lock(&self) -> ReadGuard<'_>

Obtain read access to the underlying buffer.

pub fn write_lock(&self) -> WriteGuard<'_>

Obtain write access to the underlying buffer.

pub fn to_read(&self) -> BufRead

Downgrade this to a read-only reference without cloning internal data and without changing memory locking strategy.

pub fn to_extend(&self) -> BufExtend

Transform this buffer into an extendable type.

pub fn try_unwrap(self) -> Result<Box<[u8], Global>, BufRead>

Attempt to extract the inner contents of this buf without cloning. If this memory is locked or there are clones of this reference, the unwrap will fail, returning a BufRead instance.
