Struct PluginSpec 

pub struct PluginSpec {
    pub binary: PathBuf,
    pub magic_cookie_key: String,
    pub magic_cookie_value: String,
    pub accepted_protocols: Vec<PluginProtocol>,
    pub min_port: u16,
    pub max_port: u16,
    pub kill_grace: Duration,
    pub secure: bool,
}

Parameters required to spawn and handshake with a provider plugin.

Fields

binary: PathBuf

magic_cookie_key: String

magic_cookie_value: String

accepted_protocols: Vec<PluginProtocol>

min_port: u16

max_port: u16

kill_grace: Duration

secure: bool

When true, Plugin::dial layers mTLS (go-plugin AutoMTLS) on the gRPC channel: it sets PLUGIN_CLIENT_CERT (making the provider serve TLS), then connects with rustls + the rcgen parent identity + a verifier trusting the provider’s handshake cert. When false (DEFAULT), PLUGIN_CLIENT_CERT is unset so the provider serves plaintext h2c over its local socket, and dial uses the plain h2c path. For a co-located subprocess provider talking over a process-local unix socket / loopback in the SAME pod, plaintext is both the secure boundary (the socket is filesystem- + namespace- scoped) and the known-good transport; AutoMTLS is defense-in-depth for remote/untrusted providers and is opt-in until the custom-connector h2-over-mTLS path is verified against the full provider matrix (a real protocol-6 provider closes the mTLS channel post-handshake today — surfaced precisely via H2Channel::close_reason).
