Implementations

impl FontContexts

pub fn lock_current_context(&self) -> MutexGuard<'_, FontContext>

Get access to the font context associated to the current thread.

pub(crate) fn current_worker_id(&self) -> Option<usize>

impl FontContexts

pub fn lock_context(&self, id: usize) -> MutexGuard<'_, FontContext>

Get access to any particular font context.

The id is an index between 0 and num_worker_contexts for font contexts associated to the thread pool.

pub fn lock_any_context(&self) -> MutexGuard<'_, FontContext>

pub fn num_worker_contexts(&self) -> usize
