Struct rerun::external::re_query::QueryCacheHandle

source · 
pub struct QueryCacheHandle(Arc<RwLock<RawRwLock, QueryCache>>);
Expand description

A ref-counted, inner-mutable handle to a QueryCache.

Cheap to clone.

It is possible to grab the lock behind this handle while maintaining a static lifetime, see:
