Struct PeerId 

pub struct PeerId {
    pub cert: bool,
    pub subject: Option<String>,
    pub sans: Vec<String>,
}

A verified mTLS peer’s identity, surfaced so an embedder can match a caller to a named principal rather than merely observing “a cert was presented”. All-empty for a plain / no-client-cert connection. rustls has already verified the chain; these fields are only read from the leaf certificate, so they are safe to compare against — but only because verification already happened.

Fields

cert: bool

A verified client certificate was presented (mutual TLS).

subject: Option<String>

The leaf certificate’s subject CN, if any.

sans: Vec<String>

The leaf certificate’s SANs (DNS / URI / IP); a SPIFFE X.509-SVID’s spiffe://… arrives here as a URI SAN.
