pub unsafe fn init_openssl_env_vars()Expand description
Probe for SSL certificates on the system, then configure the SSL certificate SSL_CERT_FILE
and SSL_CERT_DIR environment variables in this process for OpenSSL to use.
Preconfigured values in the environment variables will not be overwritten if the paths they point to exist and are accessible.
§Safety
This function is not safe because it mutates the process’s environment variables which is generally not safe. See the documentation in libstd for information about why setting environment variables is not safe.
If possible use the probe function and directly configure OpenSSL
methods instead of relying on environment variables.
