Implementations§

Source§

impl<Q: QueryCapability> UseQuery<Q>

Source

pub fn read(&self) -> QueryReader<Q>

Read the Query state.

This will automatically subscribe. If you want a non-subscribing method have a look at UseQuery::peek.

Source

pub fn peek(&self) -> QueryReader<Q>

Read the Query state.

This will not automatically subscribe. If you want a subscribing method have a look at UseQuery::read.

Source

pub fn suspend(&self) -> Result<Result<Q::Ok, Q::Err>, RenderError>
where Q::Ok: Clone, Q::Err: Clone,

Suspend this query until it has been settled.

This will automatically subscribe.

Source

pub async fn invalidate_async(&self) -> QueryReader<Q>

Invalidate this query and await its result.

For a sync version use UseQuery::invalidate.

Source

pub fn invalidate(&self)

Invalidate this query in the background.

For an async version use UseQuery::invalidate_async.
