pub const KERNEL_PRINCIPAL_KEY: &str = "camel.auth.principal.typed";Expand description
Exchange extension key under which install_carrier stores the
authenticated principal.
Values stored under this key are unforgeable: producing one requires an
AuthenticatedPrincipal, which no external code can construct. A
wrong-type value fails the get_extension::<AuthenticatedPrincipal>
downcast and is treated as absent.
