Struct Subject 

pub struct Subject {
    pub subject_id: Uuid,
    pub subject_type: Option<GtsTypeId>,
}

The party behind a write, in the platform’s own vocabulary rather than in a vocabulary of this gear’s own: SecurityContext’s subject_id and optional subject_type.

A subject and not a user because most writes into this gear arrive from an automation or a service integration, so a user_id member would be empty on the majority of rows and would need a second member beside it for the rest (DESIGN § API element envelope).

Fields

subject_id: Uuid

subject_type: Option<GtsTypeId>

GTS type of the acting subject, e.g. gts.cf.core.security.subject_user.v1~. Optional, matching SecurityContext, which does not always carry one.

Implementations

impl Subject

pub fn principal(&self) -> String

The producer principal this subject writes as.

One string, derived from the subject id rather than invented beside it, so “who wrote this row” (the audit envelope) and “who owns this namespace” (the ownership boundary) cannot disagree. The subject type is deliberately not part of it: the id is already unique, and folding the type in would make one principal look like two the day a producer is re-typed.

pub fn from_security_context(ctx: &SecurityContext) -> Self

The subject a SecurityContext names.
