Struct style::global_style_data::StyleThreadPool

pub struct StyleThreadPool {
    pub num_threads: Option<usize>,
    style_thread_pool: RwLock<Option<ThreadPool>>,
}

Global thread pool.

Fields

num_threads: Option<usize>

How many threads parallel styling can use. If not using a thread pool, this is set to None.

style_thread_pool: RwLock<Option<ThreadPool>>

The parallel styling thread pool.

For leak-checking purposes, we want to terminate the thread-pool, which waits for all the async jobs to complete. Thus the RwLock.

Implementations

impl StyleThreadPool

pub fn shutdown()

Shuts down the thread pool, waiting for all work to complete.

pub fn pool(&self) -> RwLockReadGuard<'_, Option<ThreadPool>>

Returns a reference to the thread pool.

We only really want to give read-only access to the pool, except for shutdown().

pub fn get_thread_handles(handles: &mut ThinVec<PlatformThreadHandle>)

Returns a list of the pool’s platform-specific thread handles.
