PinnedBuf

Struct PinnedBuf 

Source
pub struct PinnedBuf<T> { /* private fields */ }
Expand description

Typed pinned buffer.

Send + Sync — the raw pointer is page-locked host memory; the actor + this handle are the only writers, and the pool’s generation gate prevents post-restart aliasing.

Implementations§

Source§

impl<T> PinnedBuf<T>

Source

pub fn len(&self) -> usize

Source

pub fn is_empty(&self) -> bool

Source

pub fn as_ptr(&self) -> *const T

Source

pub fn as_mut_ptr(&mut self) -> *mut T

Source

pub fn as_slice(&self) -> &[T]

View as a host slice. SAFETY: relies on the buffer being initialized for the requested length. For zero-init you must fill before reading.

Source

pub fn as_mut_slice(&mut self) -> &mut [T]
