Struct SystemEnvProvider 

pub struct SystemEnvProvider;

System environment provider using std::env::var

This is the production implementation that delegates to the standard library’s environment variable access. It reads from the actual process environment.

Thread Safety

This implementation is thread-safe and can be safely shared across threads. Reading environment variables in Rust is thread-safe, though writing to them requires unsafe code.

Examples

use sublime_git_tools::{EnvProvider, SystemEnvProvider};
use std::sync::Arc;

let env = Arc::new(SystemEnvProvider);
let home = env.var("HOME").expect("HOME should be set");
println!("Home directory: {}", home);
