Implementations

impl Measure

pub fn start(name: &'static str) -> Self

pub fn stop(&mut self)

pub fn as_ns(&self) -> u64

pub fn as_us(&self) -> u64

pub fn as_ms(&self) -> u64

pub fn as_s(&self) -> f32

pub fn this<T, R, F: FnOnce(T) -> R>(
    func: F,
    args: T,
    name: &'static str
) -> (R, Self)

Measure this function

Use Measure::this() when you have a function that you want to measure. this() will start a new Measure, call your function, stop the measure, then return the Measure object along with your function’s return value.

If your function takes more than one parameter, you will need to wrap your function in a closure, and wrap the arguments in a tuple. The same thing applies to methods. See the tests for more details.

Examples

// Call a function with a single argument
let (result, measure) = Measure::this(my_function, 42, "my_func");

// Call a function with multiple arguments
let (result, measure) = Measure::this(|(arg1, arg2)| std::cmp::min(arg1, arg2), (42, 123), "minimum");

// Call a method
let foo = Foo { x: 42 };
let (result, measure) = Measure::this(|(this, args)| Foo::bar(&this, args), (&foo, baz), "Foo::bar");
