Supported targets will _always_ use their supported implementations.Á üùG D This prevents a crate from overriding a secure source of randomnessÁ üÁ+ ( (either accidentally or intentionally).Á íú üñ3 0 ## `/dev/urandom` fallback on Linux and AndroidÁ ¥ú ü©S P On Linux targets the fallback is present only if either `target_env` is `musl`,Á üýW T or `target_arch` is one of the following: `aarch64`, `arm`, `powerpc`, `powerpc64`,Á üÕQ N `s390x`, `x86`, `x86_64`. Other supported targets [require][platform-support]Á ü§U R kernel versions which support `getrandom` system call, so fallback is not needed.Á ýú ü�V S On Android targets the fallback is present only for the following `target_arch`es:Á üØR O `aarch64`, `arm`, `x86`, `x86_64`. Other `target_arch`es (e.g. RISC-V) requireÁ ü« ! sufficiently high API levels.Á Í ú üÑ X U The fallback can be disabled by enabling the `linux_disable_fallback` crate feature.Á üª S P Note that doing so will bump minimum supported Linux kernel version to 3.17 andÁ üþ * ' Android API level to 23 (Marshmallow).Á © ú ¬ ### RDRAND on x86Á à ú üÇ R O *If the `rdrand` Cargo feature is enabled*, `getrandom` will fallback to usingÁ üš K H the [`RDRAND`] instruction to get randomness on `no_std` `x86`/`x86_64`Á üæ C @ targets. This feature has no effect on other CPU architectures.Á ª ú Ü® ### WebAssembly supportÁ Ê ú üÎ ! This crate fully supports theÁ üð = : [`wasm32-wasi`](https://github.com/CraneStation/wasi) andÁ ü®!N K [`wasm32-unknown-emscripten`](https://www.hellorust.com/setup/emscripten/)Á üý!O L targets. However, the `wasm32-unknown-unknown` target (i.e. the target usedÁ üÍ"( % by `wasm-pack`) is not automaticallyÁ üö"G D supported since, from the target name alone, we cannot deduce whichÁ ü¾#J G JavaScript interface is in use (or if JavaScript is available at all).Á ‰$ú ü�$K H Instead, *if the `js` Cargo feature is enabled*, this crate will assumeÁ üÙ$L I that you are building for an environment containing JavaScript, and willÁ ü¦%P M call the appropriate methods. Both web browser (main window and Web Workers)Á ü÷%@ = and Node.js environments are supported, invoking the methodsÁ ü¸&O L [described above]
