pub struct SystemRng;Expand description
Production implementation using OS-provided cryptographically secure RNG.
§Platform support
This type is not available on wasm32-unknown-unknown. The
underlying rand/getrandom crates panic at runtime on that target
unless the consumer enables getrandom’s js feature, which is a
contract that belongs to the application, not to this auth library.
Refusing to compile here surfaces the choice at build time instead of
at the first call to rand::rng().
On wasm32-unknown-unknown, supply your own SecureRng (typically
one wrapping web_sys::Crypto::get_random_values) when constructing
the AuthnService. WASI targets (wasm32-wasi*) and the browser-via-
wasm-bindgen flow are unaffected because their getrandom backends
are wired automatically.
