Struct UpstreamTls 

pub struct UpstreamTls { /* private fields */ }

Trust settings for one upstream’s TLS backends: the certificates in a CA file instead of the WebPKI roots — for internal services behind a private CA or a self-signed certificate (nginx’s proxy_ssl_trusted_certificate). Connections are pooled per CA file, so two upstreams at the same address with different CAs never share one.

Implementations

impl UpstreamTls

pub fn from_ca_file(path: &str) -> Result<UpstreamTls, String>

Load the PEM certificates in path as the only trusted roots.
