 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: - - . Any file not matching the format, or not matching the provided prefix string, is be ignored.

   () ->  
   {      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  ()?         .   () ?;      println!  ()  S3 Update status: `{}`! '' 
, status.  (version)  ());      Ok  (()) } #  fn  ()  main) () {}  <::std::error::error>
 Separate utilities are also exposed: 
   extern

 found releases : "
;      println!  () ({ {: #?}   n
