Module fips 

FIPS provider helpers.

is_running is always available — it uses the public OSSL_PROVIDER_available API and requires no special feature flag. It is the only function needed by ordinary code that runs in FIPS mode but does not implement a FIPS provider itself.

Items under #[cfg(feature = "fips-provider")] are only compiled when the fips-provider cargo feature is enabled. They require non-public OpenSSL headers (vtable access, prov_ctx helpers, ossl_prov_is_running, etc.) and are only meaningful when you are implementing a FIPS provider.

Functions

is_running

Returns true if the FIPS provider is loaded and available in the given library context.
