Struct Principal 

#[non_exhaustive]
pub struct Principal {
    pub id: PrincipalId,
    pub bound_to: Option<PrincipalId>,
    pub status: PrincipalStatus,
    pub created_at: i64,
}

The durable principal record stored in cheers’s principal table.

Invariants (enforced by Principal::try_new and the Deserialize impl):

• kind == Camp ⇒ bound_to == Some(PrincipalId { kind: User, .. })
• kind ∈ {User, Service} ⇒ bound_to == None

A Camp { bound_to: None } JSON payload is a parse error — see the roundtrip test in this module.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: PrincipalId

bound_to: Option<PrincipalId>

status: PrincipalStatus

created_at: i64

Implementations

impl Principal

pub fn try_new( id: PrincipalId, bound_to: Option<PrincipalId>, status: PrincipalStatus, created_at: i64, ) -> Result<Self, PrincipalError>

Build a Principal and check the kind ↔ bound_to invariants.

pub fn kind(&self) -> PrincipalKind

Convenience accessor — same as self.id.kind.
