Trait ParallelBridgeBuffered 

pub trait ParallelBridgeBuffered: Sized + Iterator
where
    Self::Item: Send,
{
    // Provided method
    fn par_bridge_buffered(self) -> IntoIter<Self::Item> { ... }
}

Extension trait for iterators to convert them to parallel iterators via collection.

This is an alternative to [rayon::iter::ParallelBridge] that first collects the iterator into a Vec, then calls [IntoParallelIterator] on it. This avoids the mutex contention that can occur with par_bridge when either the iterator’s next() method is fast or the parallel tasks are fast, as par_bridge wraps the iterator in a mutex.

When to use

Use par_bridge_buffered instead of par_bridge when:

• The iterator produces items quickly
• The parallel work per item is relatively light
• The total number of items is known to be reasonable for memory

Stick with par_bridge when:

• The iterator is slow (e.g., I/O bound) and you want to overlap iteration with processing
• Memory is constrained and you cannot afford to collect all items upfront

Provided Methods

fn par_bridge_buffered(self) -> IntoIter<Self::Item>

Collects this iterator into a Vec and returns a parallel iterator over it.

See this trait’s documentation for more details.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
