[−][src]Crate hwloc2
Rust Bindings for the Hwloc library
This library is a rust binding to the hwloc C library, which provides a portable abstraction of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading.
Usage
First, add the following to your Cargo.toml
:
[dependencies]
hwloc = "0.3.0"
Next, add this to your crate root:
extern crate hwloc;
Here is a quick example which walks the Topology
and prints it out:
extern crate hwloc; use hwloc::Topology; fn main() { let topo = Topology::new().unwrap(); for i in 0..topo.depth() { println!("*** Objects at level {}", i); for (idx, object) in topo.objects_at_depth(i).iter().enumerate() { println!("{}: {}", idx, object); } } }
You can also look at more examples, if you want to run them check out the next section below.
Running Examples
The library ships with examples, and to run them you need to clone the repository
and then run them through cargo run --example=
.
$ git clone https://github.com/daschl/hwloc-rs.git
$ cd hwloc-rs
To run an example (which will download the dependencies and build it) you can
use cargo run -example=
:
$ cargo run --example=walk_tree
