# jemalloc-ctl
[![Travis-CI Status]][travis] [![Latest Version]][crates.io] [![docs]][docs.rs]
> A safe wrapper over `jemalloc`'s `mallctl*()` control and introspection APIs.
## Documentation
* [Latest release (docs.rs)][docs.rs]
## Platform support
Supported on all platforms supported by the [`tikv-jemallocator`] crate.
## Example
```no_run
use std::thread;
use std::time::Duration;
use tikv_jemalloc_ctl::{stats, epoch};
#[global_allocator]
static ALLOC: tikv_jemallocator::Jemalloc = tikv_jemallocator::Jemalloc;
fn main() {
// Obtain a MIB for the `epoch`, `stats.allocated`, and
// `atats.resident` keys:
let e = epoch::mib().unwrap();
let allocated = stats::allocated::mib().unwrap();
let resident = stats::resident::mib().unwrap();
loop {
// Many statistics are cached and only updated
// when the epoch is advanced:
e.advance().unwrap();
// Read statistics using MIB key:
let allocated = allocated.read().unwrap();
let resident = resident.read().unwrap();
println!("{} bytes allocated/{} bytes resident", allocated, resident);
thread::sleep(Duration::from_secs(10));
}
}
```
