performance_mark
is an attribute macro that adds performance (time) logging to
functions. 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!");
}
Output:
(performance_mark) test_function_logged_using_stdout took 7.177µs
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);
}
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
}
