HeapStats

✓ use dhat::HeapStats;

Initialize a heap profiler and print current heap usage.

use dhat::{HeapStats, Profiler}; let _profiler = Profiler::new_heap(); let _stats = HeapStats::get(); println!("Current heap bytes: {}", _stats.curr_bytes);

Debug

Known issues

gotchaProfiler must be kept alive for the entire profiling session; dropping it early stops profiling.

fix

Bind the Profiler to a variable with a long enough lifetime (e.g., at the start of main).

affects: >=0.3.0
