§Feature Flags

Feature	Description
`alloc (default)`	Enable features that require use of the heap, RSA in particular.
`less-safe-getrandom-custom-or-rdrand`	Treat user-provided ("custom") and RDRAND-based `getrandom` implementations as secure random number generators (see `SecureRandom`). This feature only works with `os = "none"` targets. See `register_custom_getrandom` and RDRAND on x86 for additional details.
`less-safe-getrandom-espidf`	Treat getrandom as a secure random number generator (see `SecureRandom`) on the esp-idf target. While the esp-idf target does have hardware RNG, it is beyond the scope of ring to ensure its configuration. This feature allows ring to build on esp-idf despite the likelihood that RNG is not secure. This feature only works with `os = espidf` targets. See
`std`	Enable features that use libstd, in particular `std::error::Error` integration. Implies `alloc`.
`wasm32_unknown_unknown_js`	When this feature is enabled, for the wasm32-unknown-unknown target, Web APIs will be used to implement features like `ring::rand` that require an operating environment of some kind. This has no effect for any other target. This enables the `getrandom` crate's `js` feature.
