pub fn install_default_rustls_provider()Expand description
Installs default_provider as the process-default rustls
[CryptoProvider].
This is the intended entry point when rustls (or reqwest) is compiled
without a built-in cryptography provider, such as when using reqwest’s
rustls-no-provider feature. Call it once before building any rustls
configuration.
The call is safe to repeat and never panics: the provider is installed only on the first call, and if a provider is already installed as the process default, that provider is left untouched.
