Expand description
update_me provides functionality to implement a self-updating Rust executable.
The executable can update itself by replacing the current executing file with a newer version.
This library only implements the updating mechanism itself, thereby providing full flexibility to implement different release distribution backends.
Example of updating from a file:
use update_me;
use std::fs::File;
use std::io::Read;
use anyhow::Result;
pub fn update(path: &String) -> Result<()> {
let mut file = File::open(path)?;
let mut data: Vec<u8> = Vec::new();
file.read_to_end(&mut data)?;
update_me::apply(&mut data)?;
Ok(())
}
