Function load_native_certs 

pub fn load_native_certs() -> CertificateResult

Available on crate features crypto and native-certs only.

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

Environment Variables

Env. Var.	Description
SSL_CERT_FILE	File containing an arbitrary number of certificates in PEM format.
SSL_CERT_DIR	:/; separated list of directories containing certificate files.

If either (or both) are set, certificates are only loaded from the locations specified via environment variables and not the platform-native certificate store.

Caveats

This function can be expensive: on some platforms it involves loading and parsing a ~300KB disk file, or querying the OS keychain. Prefer shared_native_trust_anchors which caches the result.
