| # This CI config checks that getrandom's backend implementation | |
| # do not contain potential panics. | |
| # | |
| # It is unclear how to implement a no-panic check for esp_idf, fuchsia, | |
| # vxworks, hermit, and solid backends, so we do not check them here, | |
| # but they still should be panic-free. We do not check wasm_js backend | |
| # since glue code generated by wasm-bindgen contains potential panics, | |
| # so resulting WASM files inevitably contain potential panics for any | |
| # code which non-trivially interacts with the JS enviroment. | |
