pub fn install_crypto_provider()Expand description
Installs the process-level rustls ring CryptoProvider exactly once.
Both the ring and aws-lc-rs backends end up compiled in through the
dependency tree; without a pinned default, rustls config builders panic on
the ambiguity. Calling this more than once (from the data plane, admin, and
the outbound client) is safe — install_default returning Err when a
provider is already installed is a harmless no-op.
