I don't know what rust-beta-* is, but the rust package I created did not
use unversioned files. There are versioned files, but afaik not in
beta. For bootstrap I had this (though it could be that this is already
Jelle's work based on my work):

(define (archive-name version platform checksum)
  (string-append "rust-stage0-" version "-" platform "-" checksum ".tar.bz2"))

(define rust-stage0-bootstrap-x86_64-archive
  (archive-name "2016-02-17-4d3eebf" "linux-x86_64" 
"d29b7607d13d64078b6324aec82926fb493f59ba"))

(define rust-stage0-bootstrap-x86_64
  (origin
    (method url-fetch)
    (uri
     (string-append "https://static.rust-lang.org/stage0-snapshots/"; 
rust-stage0-bootstrap-x86_64-archive))
    (sha256 
     (base32
      "0gk87rknijyirlhw3h34bjxzq98j0v0icp3l8flrxn5pgil8pswd"))))

(define rust-stage0-bootstrap-i386-archive
  (archive-name "2016-02-17-4d3eebf" "linux-i386" 
"5f194aa7628c0703f0fd48adc4ec7f3cc64b98c7"))

(define rust-stage0-bootstrap-i386
  (origin
    (method url-fetch)
    (uri
     (string-append "https://static.rust-lang.org/stage0-snapshots/"; 
rust-stage0-bootstrap-i386-archive))
    (sha256
     (base32
      "16fd2hmli86g1q3fyicdhh2l4aqryzxcij7sk1pljig8dr2m8hg5"))))
