Trait ForwardedUser 

pub trait ForwardedUser {
    // Required method
    fn forwarded_user(&self) -> Option<&str>;
}

Available on crate feature server only.

Read a forwarded end-user identity out of a backend’s per-request context.

The StorageProxyBackend port is generic over the host’s context type Cx, but the client arm needs to forward the caller’s identity to the upstream Unity Catalog credential vend. This trait lets a backend extract that identity from any Cx without the backend having to name the host’s concrete context type: the standalone binary’s context is a ForwardedIdentity (which forwards the validated reverse-proxy user), while a host that has no forwarded identity (or the unit context () used by tests) simply returns None.

Required Methods

fn forwarded_user(&self) -> Option<&str>

The forwarded end-user name, or None when the request is anonymous / carries no forwarded identity.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl ForwardedUser for ()

The unit context carries no identity — always anonymous.
