Struct ArcConditionalStatefulBiTransformer 

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

ArcConditionalStatefulBiTransformer struct

A thread-safe conditional bi-transformer that only executes when a bi-predicate is satisfied. Uses ArcStatefulBiTransformer and ArcBiPredicate for shared ownership across threads.

This type is typically created by calling ArcStatefulBiTransformer::when() and is designed to work with the or_else() method to create if-then-else logic.

Features

• Shared Ownership: Cloneable via Arc, multiple owners allowed
• Thread-Safe: Implements Send + Sync, safe for concurrent use
• Conditional Execution: Only transforms when bi-predicate returns true
• Chainable: Can add or_else branch to create if-then-else logic

Examples

use prism3_function::{StatefulBiTransformer, ArcStatefulBiTransformer};

let add = ArcStatefulBiTransformer::new(|x: i32, y: i32| x + y);
let multiply = ArcStatefulBiTransformer::new(|x: i32, y: i32| x * y);
let conditional = add.when(|x: &i32, y: &i32| *x > 0).or_else(multiply);

let conditional_clone = conditional.clone();

assert_eq!(conditional.apply(5, 3), 8);
assert_eq!(conditional_clone.apply(-5, 3), -15);

Implementations

impl<T, U, R> ArcConditionalStatefulBiTransformer<T, U, R>

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

pub fn or_else<F>( &self, else_transformer: F, ) -> ArcStatefulBiTransformer<T, U, R>

where F: StatefulBiTransformer<T, U, R> + Send + Sync + 'static,

Adds an else branch

Executes the original bi-transformer when the condition is satisfied, otherwise executes else_transformer.

Parameters

• else_transformer - The bi-transformer for the else branch

Returns

Returns a new bi-transformer with if-then-else logic
