Struct MemorySubscriptionFilter 

pub struct MemorySubscriptionFilter { /* private fields */ }

In memory representation of a subscription filter. This is what we will use to evaluate whether a given subscription matches an incoming event.

Implementations

impl MemorySubscriptionFilter

pub async fn new<Resolver: SearchParameterResolve>( tenant_id: &TenantId, project_id: &ProjectId, resolver: Arc<Resolver>, value: Subscription, ) -> Result<Self, OperationOutcomeError>

Creates a MemorySubscriptionFilter from a subscription.

Resolves and validates the search parameters specified in the subscription criteria and constructs the corresponding FHIRPath-based filter.

Errors

Returns an [OperationOutcomeError] if:

• the subscription criteria has an invalid format;
• the criteria contains an invalid resource type;
• a search parameter cannot be resolved for the resource type;
• a chained search parameter is used;
• a resolved search parameter does not have a FHIRPath expression;
• an unsupported result parameter is present in the criteria; or
• the subscription does not contain criteria.

Arguments

• tenant_id - The tenant owning the subscription.
• project_id - The project owning the subscription.
• resolver - Resolver used to look up search parameters.
• value - The subscription from which to construct the filter.
