Struct Scope 

pub struct Scope {
    pub column: String,
    pub value: Option<SqlValue>,
    pub session: Option<SqlValue>,
    pub mode: ScopeMode,
    pub keys: TableKeys,
}

A host-resolved in-site row-tenancy scope — the applied side of the resolved principal. value is the resolved own-tenant fact (None ⇒ the actor has no tenant, e.g. a purely anonymous Session-only request); session is the resolved anonymous-session fact (R3); mode decides how the tenant axis restricts the operation; keys resolves the tenant column(s) per table (the project schema — R2/R3/D2). Injected by the host on every query node (top-level, UNION branch, INSERT … SELECT source), never guest-set. The fail-closed “no fact for a scope that needs one” decision is made per table in the injector (a Column table with no tenant value denies; a TenantOrSession table falls back to whichever axis fact is present).

Fields

column: String

value: Option<SqlValue>

The resolved own-tenant value, or None for an anonymous (Session-only) actor.

session: Option<SqlValue>

The resolved anonymous-session value (R3), or None when the request carries no session fact. Only consulted for a TableScope::TenantOrSession table.

mode: ScopeMode

keys: TableKeys

Per-table key resolution; TableKeys::Uniform (the default) preserves the pre-schema single-column behavior (every table scopes on column).

Implementations

impl Scope

pub fn is_target(&self) -> bool

Whether this scope is a target scope (PerTableTarget — reading/writing another tenant B’s public subset, R4/D8), vs. the caller’s own.

Trait Implementations

impl Clone for Scope

fn clone(&self) -> Scope

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Scope

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Scope

fn eq(&self, other: &Scope) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
