Struct sodoken::BufExtend

pub struct BufExtend(pub Arc<dyn AsBufExtend>);

A concrete extendable buffer type that may or may not be mem_locked.

Tuple Fields

0: Arc<dyn AsBufExtend>

Implementations

impl BufExtend

pub fn new_no_lock(initial_capacity: usize) -> Self

Construct a new extendable buffer with given capacity. It’s ok / still fairly efficient to set this to zero.

pub fn extend_lock(&self) -> ExtendGuard<'_>

Obtain access to extend the underlying buffer.

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 try_unwrap(self) -> Result<Box<[u8]>, 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.

Performs copy-assignment from source.

impl Debug for BufExtend
