I&#x27;ve seen rust compiler bug once and that was long before 1.0. The only issue now is that some important API&#x27;s are not yet declared stable (RFC still being open), so many 3rd-party libraries target nightly and won&#x27;t work in stable. This is however matter or 1 or 2 releases, and proves that rust developers take this matter seriously and don&#x27;t wont to stabilize anything they aren&#x27;t 100% sure.
For all practical purposes rust is usable now, and more and more people are using it - certainly more then 3. Generally looking at rust projects on github,
most of issues are feature requests. I don&#x27;t see issues with crashes or panics,
while I know plenty for similar projects written in C, at least in their early days.
