Struct ArcBiTransformer 

pub struct ArcBiTransformer<T, U, R> { /* private fields */ }

ArcBiTransformer - thread-safe bi-transformer wrapper

A thread-safe, clonable bi-transformer wrapper suitable for multi-threaded scenarios. Can be called multiple times and shared across threads.

Features

• Based on: Arc<dyn Fn(T, U) -> R + Send + Sync>
• Ownership: Shared ownership via reference counting
• Reusability: Can be called multiple times (each call consumes its inputs)
• Thread Safety: Thread-safe (Send + Sync required)
• Clonable: Cheap cloning via Arc::clone

Implementations

impl<T, U, R> ArcBiTransformer<T, U, R>

where T: 'static, U: 'static, R: 'static,

pub fn new<F>(f: F) -> Self

where F: Fn(T, U) -> R + Send + Sync + 'static,

Creates a new bi-transformer.
