Struct UserObject 

pub struct UserObject { /* private fields */ }

A refcounted user object.

Implementations

impl UserObject

pub fn new<F>(destroy: F, initial_refcount: u32) -> Result<Self>

where F: FnOnce() + Send + 'static,

Create a user object whose destructor is destroy. initial_refcount must be >= 1.

pub fn retain(&self, count: u32) -> Result<()>

Safe wrapper for cudaUserObjectRetain. Add count references to this user object.

pub fn release(&self, count: u32) -> Result<()>

Safe wrapper for cudaUserObjectRelease. Drop count references from this user object; when the count reaches zero the destructor supplied at creation runs.

pub fn as_raw(&self) -> cudaUserObject_t

Raw cudaUserObject_t handle. Use with care — owned by self.

Trait Implementations

impl Debug for UserObject

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

Formats the value using the given formatter.

impl Drop for UserObject

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
