# rspawn
A crate to fetch latest version from crates.io and update your binary.
Similar crates do similar things, but none had the specific mix I needed.
## Usage
Run example with `cargo run --example usage`.
See [examples/usage.rs](./examples/usage.rs):
```rust
use rspawn::relaunch_program;
use std::io;
fn main() {
let custom_confirm = |version: &str| {
println!("A new version {} is available. Would you like to install it? (yes/n): ", version);
let mut response = String::new();
io::stdin().read_line(&mut response).unwrap();
response.trim().to_lowercase() == "yes"
};
#[allow(non_snake_case)]
let check_if_executed_from_PATH = true; // Only ask for update when called from PATH
if let Err(e) = relaunch_program(None, Some(custom_confirm), check_if_executed_from_PATH) {
eprintln!("Error: {}", e);
}
}
```
