Generation

basil_core::core::state

Struct Generation 

Source 
pub struct Generation { /* private fields */ }
Expand description

One coherent snapshot of the reloadable policy surface.

A Generation bundles the Catalog, ResolvedPolicy index, and export-resolved Config tables that together drive a Pdp decision, plus a monotonic id that names this snapshot in the audit trail. It is the unit that BrokerState swaps atomically on reload: an operation that pins one Generation sees an internally consistent (catalog, policy, config) triple for its entire lifetime, so a concurrent reload can never mix an old catalog with a new policy.

Implementations§

Source§

impl Generation

Source

pub fn new( id: u64, catalog: impl Into<Arc<Catalog>>, policy: ResolvedPolicy, config: Config, ) -> Self

Bundle a (catalog, policy, config) triple under a generation id.

Source

pub const fn id(&self) -> u64

This generation’s monotonic id (for the audit record / status probe).

Source

pub fn pdp(&self) -> Pdp<'_>

A Pdp borrowing this generation’s catalog/policy/config for one decision.

The PDP is Copy and holds only shared borrows into this generation, so this is a cheap view, not a clone. The borrow ties the PDP to the generation snapshot, keeping the whole decision coherent.

Source

pub const fn config(&self) -> &Config

The export-resolved config tables (for name(num) audit rendering).

Source

pub const fn policy(&self) -> &ResolvedPolicy

This generation’s resolved authorization policy.

Source

pub fn catalog(&self) -> &Catalog

This generation’s loaded Catalog.

Used by the reload engine (basil-y3e.2) to compare the candidate’s restart-only routing shape against the currently-serving generation.
