Function rustls_native_certs::load_native_certs

pub fn load_native_certs() -> Result<Vec<CertificateDer<'static>>, Error>

Load root certificates found in the platform’s native certificate store.

If the SSL_CERT_FILE environment variable is set, certificates (in PEM format) are read from that file instead.

This function fails in a platform-specific way, expressed in a std::io::Error.

This function can be expensive: on some platforms it involves loading and parsing a ~300KB disk file. It’s therefore prudent to call this sparingly.
