A system handler to interact with processes.
Support the following platforms:
* Linux
* Raspberry
* Android
* macOS
* Windows
It also compiles for Android but never been tested on it.
### Running on Raspberry
It'll be difficult to build on Raspberry. A good way-around is to be build on Linux before sending it to your Raspberry.
First install the arm toolchain, for example on Ubuntu: `sudo apt-get install gcc-multilib-arm-linux-gnueabihf`.
Then configure cargo to use the corresponding toolchain:
```bash
cat << EOF > ~/.cargo/config
[target.armv7-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"
EOF
```
Finally, cross compile:
```bash
rustup target add armv7-unknown-linux-gnueabihf
cargo build --target=armv7-unknown-linux-gnueabihf
```
## Code example
You have an example into the `examples` folder. Just run `cargo run` inside the `examples` folder to start it. Otherwise, here is a little code sample:
```rust
use sysinfo::{NetworkExt, NetworksExt, System, SystemExt};
let mut sys = System::new();
// We display the disks:
println!("=> disk list:");
for disk in sys.get_disks() {
println!("{:?}", disk);
}
// Network data:
for (interface_name, data) in sys.get_networks() {
println!("{}: {}/{} B", interface_name, data.get_income(), data.get_outcome());
}
// Components temperature:
for component in sys.get_components() {
println!("{:?}", component);
}
// Memory information:
println!("total memory: {} KiB", sys.get_total_memory());
println!("used memory : {} KiB", sys.get_used_memory());
println!("total swap : {} KiB", sys.get_total_swap());
println!("used swap : {} KiB", sys.get_used_swap());
// Number of processors
println!("NB processors: {}", sys.get_processors().len());
// To refresh all system information:
sys.refresh_all();
```
## C interface
It's possible to use this crate directly from C. Take a look at the `Makefile` and at the `examples/src/simple.c` file.
To build the C example, just run:
```bash
> make
> ./simple
# If needed:
> LD_LIBRARY_PATH=target/release/ ./simple
```
### Benchmarks
You can run the benchmarks locally with rust **nightly** by doing:
```bash
> cargo bench
```
