Time measure for Rust functions

It will simply print execution time of a function

Usage

[dependencies]
exec_time = "0.1.4"

Examples

In print log, it is printing Time <prefix>::<function_name>::<suffix>: <execution time> mills

Example 1

It will always print.

#[macro_use]
extern crate exec_time;

#[exec_time]
fn login() {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

fn main() {
    login()
}

Time login: 102 mills

Example 2

It will print only in debug mode.

#[macro_use]
extern crate exec_time;

#[exec_time(print = "debug")]
fn login() {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

fn main() {
    login()
}

Time login: 102 mills

Example 3

It will never print.

#[macro_use]
extern crate exec_time;

#[exec_time(print = "never")]
fn login() {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

fn main() {
    login()
}

Example 4

It will print, prefix and suffix with function name.

#[macro_use]
extern crate exec_time;

#[exec_time(print = "always", prefix = "user/lib", suffix="route")]
fn login() {
    std::thread::sleep(std::time::Duration::from_millis(100));
}

fn main() {
    login()
}

Time user/lib::login::route: 102 mills

Note Point

Here print, prefix and suffix all are optional field. Default value of print is always. print may be always(by default), debug, never. If the value is always it will print always. If value is debug, It will print only in debug mode else, It will never print.
