Expand description

Configuration to be used with crate::QueryClient and individual query scopes.

Implementations§

Source§

impl QueryOptions

Source

pub fn new() -> Self

Create new QueryOptions with default values.

Source

pub fn with_stale_time(self, stale_time: Duration) -> Self

Set the duration that should pass before a query is considered stale.

Once stale, after any new interaction with the query, a new resource using it, declarative interactions etc, the query will be refetched in the background, and update active resources.

Default: never

Source

pub fn with_gc_time(self, gc_time: Duration) -> Self

Set the duration that should pass before an unused query is garbage collected.

After this time, if the query isn’t being used by any resources, the query will be removed from the cache, to minimise the cache’s size. If the query is in active use, the gc will be scheduled to check again after the same time interval.

To never garbage collect, set std::time::Duration::MAX.

Default: 5 minutes

Source

pub fn with_refetch_interval(self, refetch_interval: Duration) -> Self

Set the interval after which to automatically refetch the query if there are any active resources.

If the query is being used by any resources, it will be invalidated and refetched in the background, updating active resources according to this interval.

Default: No refetching

Source

pub fn stale_time(&self) -> Duration

The duration that should pass before a query is considered stale.

Once stale, after any new interaction with the query, a new resource using it, declarative interactions etc, the query will be refetched in the background, and update active resources.

Default: never

Source

pub fn gc_time(&self) -> Duration

The duration that should pass before an unused query is garbage collected.

After this time, if the query isn’t being used by any resources, the query will be removed from the cache, to minimise the cache’s size. If the query is in active use, the gc will be scheduled to check again after the same time interval.

Default: 5 minutes

Source

pub fn refetch_interval(&self) -> Option<Duration>

The interval (if any) after which to automatically refetch the query if there are any active resources.

If the query is being used by any resources, it will be invalidated and refetched in the background, updating active resources according to this interval.

Default: No refetching
