Absolutely. Milestones are a better indicator of that: https://github.com/mozilla/rust/issues/milestones

Specifically, maturity #5 - production ready: https://github.com/mozilla/rust/issues?milestone=16&state=op...

  > The purpose of this milestone is to represent a high degree of confidence the
  > language's suitability for industrial use due to a high level of measured
  > correctness and performance in the tests.
  
  > In other words, for each of the aspects described in the "well covered"
  > milestone, and for each supported target platform, test success and benchmark
  > performance has reached a level deemed suitable for production use in
  > environments with substantial business consequences for major defects or low
  > performance. Where possible, performance benchmarks are linked to equivalent
  > benchmarks in competitive languages, and rust is sufficiently close to
  > equivalent in performance.
