A simple cross-platform way to get information about the currently running system.
This simple example:
// examples/ex.rs // * use `cargo run --example ex` to execute this example // spell-checker:ignore (API) nodename osname sysname use platform_info::*; fn main() { let info = PlatformInfo::new().expect("Unable to determine platform info"); // println!("info={:#?}", info); println!("{}", info.sysname().to_string_lossy()); println!("{}", info.nodename().to_string_lossy()); println!("{}", info.release().to_string_lossy()); println!("{}", info.version().to_string_lossy()); println!("{}", info.machine().to_string_lossy()); println!("{}", info.processor().to_string_lossy()); println!("{}", info.osname().to_string_lossy()); }
should display something like:
Linux
hostname
5.10.0-8-amd64
#1 SMP Debian 5.10.46-4 (2021-08-03)
x86_64
x86_64
GNU/Linux
Using
cargo run --example exwill build and execute this example code.
To cross-compile and run the example under WASI, first install wasmtime:
curl https://wasmtime.dev/install.sh -sSf | bashThen build and run:
cargo build --target wasm32-wasip1 --example ex wasmtime target/wasm32-wasip1/debug/examples/ex.wasm
This should display:
wasi
localhost
0.0.0
0.0.0
wasm32

WASI
