Struct devtimer::ComplexTimer

pub struct ComplexTimer { /* fields omitted */ }

Complex Timer

A complex timer wraps around a map of timer names and their corresponding SimpleTimer instances.

Implementations

impl ComplexTimer

pub fn new() -> Self

Return a new ComplexTimer instance

pub fn create_timer(
    &mut self,
    timer_name: &'static str
) -> Result<(), &'static str>

Create a new timer tag. If the timer tag already exists, then this function returns an error.

pub fn start_timer(
    &mut self,
    timer_name: &'static str
) -> Result<(), &'static str>

Start a timer with tag timer_name. If this timer tag doesn't exist, then it returns an error

pub fn stop_timer(
    &mut self,
    timer_name: &'static str
) -> Result<(), &'static str>

Stop a timer with tag timer_name. If this timer tag doesn't exist, then it returns an error

pub fn time_in_secs(&self, timer_name: &'static str) -> Option<u64>

Get the time in seconds for a timer with tag timer_name

pub fn time_in_millis(&self, timer_name: &'static str) -> Option<u128>

Get the time in milliseconds for a timer with tag timer_name

pub fn time_in_micros(&self, timer_name: &'static str) -> Option<u128>

Get the time in microseconds for a timer with tag timer_name

pub fn time_in_nanos(&self, timer_name: &'static str) -> Option<u128>

Get the time in nanoseconds for a timer with tag timer_name

pub fn delete_timer(
    &mut self,
    timer_name: &'static str
) -> Result<(), &'static str>

Delete a timer with tag timer_name

pub fn clear_timers(&mut self)

Delete all set timers

pub fn print_results(&self)

Print all results in the following format:

timerx - 120 ns
timery - 1233 ns
...

pub fn iter(&self) -> Iter<&'static str, SimpleTimer>

Returns an iterator of timer tags and the corresponding SimpleTimer instances

Example

// Assume some `ComplexTimer` instanc `dt` exists
let mut dt = DevTime::new_complex();
for (name, timer) in dt.iter() {
    println!("Timer: {} took {} ns", name, timer.time_in_nanos());
}
