Macro processor 

macro_rules! processor {
    ($struct_name:ident, $type:ty, $process_fn:expr) => { ... };
}

Creates a stateless, data-transforming processor struct.

This macro generates a struct that implements the Processor<T> trait, taking data of a specific type, processing it with a given function, and returning data of the same type.

Parameters

• $struct_name: The name for the new processor struct.
• $type: The type of data the processor will operate on.
• $process_fn: A function or closure that takes a value of $type and returns a new value of $type.

Examples

use type_flow_macros::processor;
use type_flow_traits::Processor;

fn to_uppercase(s: String) -> String {
    s.to_uppercase()
}

processor!(UppercaseProcessor, String, to_uppercase);

let processed = UppercaseProcessor::process("hello".to_string());
assert_eq!(processed, "HELLO");
