Struct AvailabilityScopeRead 

pub struct AvailabilityScopeRead { /* private fields */ }

The real, database-backed availability scope read. Implements AvailabilityScopePort so a composition can hold the trait and swap adapters (the refusing default in tests, this service in production).

Implementations

impl AvailabilityScopeRead

pub fn new(db_pool: PgPool) -> Self

Trait Implementations

impl AvailabilityScopePort for AvailabilityScopeRead

fn display_availability<'life0, 'life1, 'async_trait>( &'life0 self, item_ids: &'life1 [Uuid], warehouse_id: Uuid, ) -> Pin<Box<dyn Future<Output = Result<Vec<ScopedAvailability>, AvailabilityScopeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Display scope: fresh per-item availability at the pivot warehouse, complete over item_ids in input order (absent items zeroed — an unreceived item is unavailable, not an error).

fn checkout_free_qty<'life0, 'life1, 'async_trait>( &'life0 self, demands: &'life1 [CheckoutDemand], warehouse_id: Uuid, ) -> Pin<Box<dyn Future<Output = Result<Vec<CheckoutFreeQty>, AvailabilityScopeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Checkout scope: fresh per-item availability at the (possibly pickup-overridden) pivot warehouse minus the caller’s own held quantities, floored at zero. Complete over the demand list’s items.

fn sold_out<'life0, 'life1, 'async_trait>( &'life0 self, item_ids: &'life1 [Uuid], warehouse_id: Uuid, ) -> Pin<Box<dyn Future<Output = Result<SoldOutVerdict, AvailabilityScopeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Sold-out verdict over the WHOLE item set (WSC’s first-variant-only template check is the bug class this refuses to re-express): sold_out = no member has availability. Policy (may an out-of-stock item still be ordered?) stays with the caller — this is raw stock truth.

impl Clone for AvailabilityScopeRead

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
