The three Emscripten targets -//! `asmjs-unknown-emscripten`, `wasm32-unknown-emscripten`, and -//! `wasm32-experimental-emscripten` use Emscripten's `/dev/random` emulation. -//! The WASI target `wasm32-wasi` uses the [`__wasi_random_get`][17] function -//! defined by the WASI standard. -//! -//! Getrandom also supports `wasm32-unknown-unknown` by directly calling -//! JavaScript methods. Rust currently has two ways to do this: [bindgen] and -//! [stdweb]. Getrandom supports using either one by enabling the -//! `wasm-bindgen` or `stdweb` crate features. Note that if both features are -//! enabled, `wasm-bindgen` will be used. If neither feature is enabled, calls -//! to `getrandom` will always fail at runtime. -//! -//! [bindgen]: https://github.com/rust-lang/rust-bindgen -//! [stdweb]: https://github.com/koute/stdweb -//! -//! ## Early boot -//! -//! It is possible that early in the boot process the OS hasn't had enough time -//! yet to collect entropy to securely seed its RNG, especially on virtual -//! machines. -//! -//! Some operating systems always block the thread until the RNG is securely -//! seeded. This can take anywhere from a few seconds to more than a minute. -//! Others make a best effort to use a seed from before the shutdown and don't -//! document much. -//! -//! A few, Linux, NetBSD and Solaris, offer a choice between blocking and -//! getting an error; in these cases we always choose to block. -//! -//! On Linux (when the `getrandom` system call is not available) and on NetBSD -//! reading from `/dev/urandom` never blocks, even when the OS hasn't collected -//! enough entropy yet. To avoid returning low-entropy bytes, we first read from -//! `/dev/random` and only switch to `/dev/urandom` once this has succeeded. -//! -//! # Error handling -//! -//! We always choose failure over returning insecure "random" bytes. In general, -//! on supported platforms, failure is highly unlikely, though not impossible. -//! If an error does occur, then it is likely that it will occur on every call to -//! `getrandom`, hence after the first successful call one can be reasonably -//! confident that no errors will occur. -//! -//! On unsupported platforms, `getrandom` always fails. See the [`Error`] type -//! for more information on what data is returned on failure. -//! -//!
