Build Status

microprofile-rust

microprofile-rust is a profiler for profiling and optimizing multithreaded game code

Its a rust port of microprofile:

Which in turn depends on the excellent distorm project

Integration

Add microprofile as a dependency:

[dependencies]
microprofile = "0.2.1"

microprofile is meant to be called from a game engine every frame. to do this you call microprofile::flip every frame. If your program is not framebased, you can use microprofile::start_auto_flip(delay_in_ms) and microprofile::stop_auto_flip(), which will make microprofile call this function itself every delay_in_ms ms.

To time some code, you insert a scope in your program

microprofile::scope!("group-name", "timer-name");

All of microprofile-rust's functions are available as macros. Use the feature "disabled" to fully disable all the macros, and remove all the microprofile code instrumentation

[dependencies.microprofile]
version = "0.2.1"
features = ["disabled"]

Limitations

As of version 0.2.1 only a subset of microprofile is supported:

  • Scope timers are supported
  • Dynamic instrumentation is supported
  • Windows, Linux and OSX is supported

The following features are not supported:

  • GPU timers
  • Counters

Using the UI

Please see the microprofile documentation : https://github.com/jonasmr/microprofile
