Self_update: In-place updates for Rust executables

self_update

self_update provides updaters for updating rust executables in-place from various release distribution backends.

Usage

Update (replace) the current executable with the latest release downloaded from https://api.github.com/repos/jaemk/self_update/releases/latest. Note, the trust project provides a nice setup for producing release-builds via CI (travis/appveyor).

#[macro_use] extern crate self_update; fn update() -> Result<(), Box<::std::error::Error>> { let status = self_update::backends::github::Update::configure() .repo_owner("jaemk") .repo_name("self_update") .bin_name("self_update_example") .show_download_progress(true) .current_version(cargo_crate_version!()) .build()? .update()?; println!("Update status: `{}`!", status.version()); Ok(()) }

Run the above example to see self_update in action: cargo run --example github

Amazon S3 is also supported as the backend to check for new releases. Provided a bucket_name and asset_prefix string, self_update will look up all matching files using the following format as a convention for the filenames: <asset name>-<semver>-<platform/target>.<extension>. Any file not matching the format, or not matching the provided prefix string, is be ignored.

fn update() -> Result<(), Box<::std::error::Error>> { let status = self_update::backends::s3::Update::configure() .bucket_owner("self_update_releases") .asset_prefix("self_update") .region("eu-west-2") .bin_name("self_update_example") .show_download_progress(true) .current_version(cargo_crate_version!()) .build()? .update()?; println!("S3 Update status: `{}`!", status.version()); Ok(()) } # fn main() { } 

Separate utilities are also exposed:

extern crate self_update; fn update() -> Result<(), Box<::std::error::Error>> { let releases = self_update::backends::github::ReleaseList::configure() .repo_owner("jaemk") .repo_name("self_update") .build()? .fetch()?; println!("found releases:"); println!("{:#?}\n", releases); // get the first available release let asset = releases[0] .asset_for(&self_update::get_target()).unwrap(); let tmp_dir = self_update::TempDir::new_in(::std::env::current_dir()?, "self_update")?; let tmp_tarball_path = tmp_dir.path().join(&asset.name); let tmp_tarball = ::std::fs::File::open(&tmp_tarball_path)?; self_update::Download::from_url(&asset.download_url) .download_to(&tmp_tarball)?; let bin_name = std::path::PathBuf::from("self_update_bin"); self_update::Extract::from_source(&tmp_tarball_path) .archive(self_update::ArchiveKind::Tar(Some(self_update::Compression::Gz))) .extract_file(&tmp_dir.path(), &bin_name)?; let tmp_file = tmp_dir.path().join("replacement_tmp"); let bin_path = tmp_dir.path().join(bin_name); self_update::Move::from_source(&bin_path) .replace_using_temp(&tmp_file) .to_dest(&::std::env::current_exe()?)?; Ok(()) }
