From d621533f15871ce233e3a1dcc0fb10a631090678 Mon Sep 17 00:00:00 2001 From: Aleksey Kladov Date: Wed, 26 Jun 2019 11:11:28 +0300 Subject: add cpuprofile to ra_prof Now, one can use `let _p = ra_prof::cpu_profiler()` to capture profile of a block of code. This is not an out of the box experience, as that relies on gperfools See the docs on https://github.com/AtheMathmo/cpuprofiler for more! --- Cargo.lock | 52
