Struct DispatchQueue 

pub struct DispatchQueue { /* private fields */ }

Available on crate feature dispatch only.

A wrapper around GCD DispatchQueue

This allows you to provide a custom dispatch queue for stream output handling instead of using the default queue.

Example

use apple_cf::dispatch_queue::{DispatchQueue, DispatchQoS};

let queue = DispatchQueue::new("com.myapp.capture", DispatchQoS::UserInteractive);

Implementations

impl DispatchQueue

pub fn new(label: &str, qos: DispatchQoS) -> Self

Creates a new dispatch queue with the specified label and QoS

Arguments

• label - A string label for the queue (e.g., “com.myapp.capture”)
• qos - The quality of service level for the queue

Examples

use apple_cf::dispatch_queue::{DispatchQueue, DispatchQoS};

let queue = DispatchQueue::new("com.myapp.capture", DispatchQoS::UserInteractive);
// Use the queue with SCStream's add_output_handler_with_queue

The label is truncated at its first NUL byte.

Panics

Panics if queue creation fails

pub fn concurrent(label: &str, qos: DispatchQoS) -> Self

pub fn main() -> Self

pub fn global(qos: DispatchQoS) -> Self

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

Returns the raw pointer to the dispatch queue

This is used internally for FFI calls (and for testing)

pub unsafe fn exec_async_f( &self, context: *mut c_void, work: unsafe extern "C" fn(*mut c_void), )

pub unsafe fn exec_after_f( &self, delay: Duration, context: *mut c_void, work: unsafe extern "C" fn(*mut c_void), )

Trait Implementations

impl Clone for DispatchQueue

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DispatchQueue

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

Formats the value using the given formatter.

impl Display for DispatchQueue

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

Formats the value using the given formatter.

impl Drop for DispatchQueue

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.
