Struct ActAs 

pub struct ActAs {
    pub namespace: String,
    pub space_id: String,
    pub grant: u32,
}

The per-request effective-identity selector the gateway sets when running a BrainPool::shared service pool: build one with ActAs { namespace, space_id } (or the SDK request builders’ .act_as(..)) to run each op as a resolved tenant on behalf of the trusted service principal. Re-exported so a gateway consuming brain_edge need not also name brain_db_sdk directly. Per-request effective-identity selector carried on data-plane op requests. When present, the op runs as this (namespace, space_id) on behalf of the authenticated connection principal; when the field is absent (the common case, omitted on the wire) the op runs as the connection’s own key-bound identity.

Honored server-side only when the connection principal holds can_act_as and namespace lies within its granted allowlist — otherwise the op is rejected with ErrorCodeWire::ActAsDenied. This is the wire form only; the trust model is enforced by the server, not this codec.

Fields

namespace: String

Effective namespace. Must be within the principal’s allowlist.

space_id: String

Structured, opaque effective-space selector (e.g. "support-bot:user123") — a CBOR text string on the wire. The server derives the 16-byte storage space id from it at ingress. An empty string selects the connection’s key-bound space.

grant: u32

Extra capability bits granted to the effective caller for this op, on top of the standard space mask. Only SCHEMA_UPLOAD (1 << 4) and ADMIN (1 << 5) are grantable, and only when the connection principal holds them itself. 0 is omitted on the wire, so a grant-less selector encodes byte-identically to the pre-grant form.
