Attribute Macro performance_mark

#[performance_mark]

performance_mark is an attribute macro that adds performance (time) logging to methods. By default, it uses println!, but can be configured to use a custom method.

Basic example:

use performance_mark_attribute::performance_mark;

#[performance_mark]
fn test_function_logged_using_stdout() {
   println!("Hello!");
}

Example with a custom logging method:

use performance_mark_attribute::{performance_mark, LogContext}

#[performance_mark(log_with_this)]
fn test_function_logged_using_custom_function() {
   println!("Hello!");
}

fn log_with_this(ctx: LogContext) {
    println!("Function: {} , Time: {}ms", ctx.function, ctx.duration);
}

Example with a custom async logging method:

use performance_mark_attribute::{performance_mark, LogContext}

#[performance_mark(async log_with_this)]
fn test_function_logged_using_custom_function() {
   println!("Hello!");
}

async fn log_with_this(ctx: LogContext) {
    // Log asynchronously
}
