Enum QueryBeginResult 

pub enum QueryBeginResult {
    Started {
        request_id: RequestId,
        status: QueryStatus,
        replaced_request_id: Option<RequestId>,
    },
    CacheHit,
    StaleCacheHit {
        request_id: RequestId,
        status: QueryStatus,

    },
    IgnoredWhileLoading {
        active_request_id: RequestId,
    },
}

Available on crate feature core only.

The result of calling begin_request on a query resource.

Variants

Started

A new request was started.

Fields

request_id: RequestId

status: QueryStatus

replaced_request_id: Option<RequestId>

CacheHit

Cache is fresh — no fetch needed.

StaleCacheHit

Stale data was served and a background revalidation was started.

The caller should:

1. Return the existing stale data to the consumer immediately.
2. Use the request_id to perform a background fetch.
3. Complete the request normally via complete_success/complete_failure.

Fields

request_id: RequestId

status: QueryStatus

replaced_request_id: Option<RequestId>

IgnoredWhileLoading

A request is already loading and the policy is IgnoreWhileLoading.

Fields

active_request_id: RequestId
