Struct MTArena 

pub struct MTArena<T>
where
    T: Debug + Send + Sync + Clone + 'static,
{ /* private fields */ }

MTArena is built on top of Arena but with support for sharing the arena between threads. Also supports tree walking on a separate thread w/ a lambda that’s supplied.

Implementations

impl<T> MTArena<T>

where T: Debug + Send + Sync + Clone + 'static,

pub fn new() -> Self

pub fn get_arena_arc(&self) -> ShareableArena<T>

pub fn tree_walk_parallel( &self, node_id: usize, walker_fn: Arc<WalkerFn<T>>, traversal_kind: TraversalKind, ) -> JoinHandle<ResultUidList>

walker_fn is a closure that captures variables. It is wrapped in an Arc to be able to clone that and share it across threads. More info:
