Expand description

Extension trait providing readonly bi-consumer composition methods for closures

Provides and_then and other composition methods for all closures implementing Fn(&T, &U), enabling direct method chaining on closures without explicit wrapper types.

§Features

  • Natural Syntax: Chain operations directly on closures
  • Returns BoxReadonlyBiConsumer: Composition results can be further chained
  • Zero Cost: No overhead when composing closures
  • Automatic Implementation: All Fn(&T, &U) closures get these methods automatically

§Examples

use prism3_function::{ReadonlyBiConsumer, FnReadonlyBiConsumerOps};

let chained = (|x: &i32, y: &i32| {
    println!("First: {}, {}", x, y);
}).and_then(|x: &i32, y: &i32| {
    println!("Second: sum = {}", x + y);
});
chained.accept(&5, &3);

Provided Methods§

Source

fn and_then<C>(self, next: C) -> BoxReadonlyBiConsumer<T, U>
where Self: 'static, C: ReadonlyBiConsumer<T, U> + 'static, T: 'static, U: 'static,

Chains another readonly bi-consumer in sequence

Returns a new consumer executing the current operation first, then the next operation. Consumes the current closure and returns BoxReadonlyBiConsumer<T, U>.

§Type Parameters
  • C - The type of the next consumer
§Parameters
  • next - The consumer to execute after the current operation
§Returns

Returns the composed BoxReadonlyBiConsumer<T, U>

§Examples
use prism3_function::{ReadonlyBiConsumer, FnReadonlyBiConsumerOps};

let chained = (|x: &i32, y: &i32| {
    println!("First: {}, {}", x, y);
}).and_then(|x: &i32, y: &i32| {
    println!("Second: sum = {}", x + y);
}).and_then(|x: &i32, y: &i32| {
    println!("Third: product = {}", x * y);
});

chained.accept(&5, &3);

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
