| 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.

|
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.
