Struct object_store::limit::LimitStore

pub struct LimitStore<T: ObjectStore> { /* private fields */ }

Store wrapper that wraps an inner store and limits the maximum number of concurrent object store operations. Where each call to an ObjectStore member function is considered a single operation, even if it may result in more than one network call

// Create an in-memory `ObjectStore` limited to 20 concurrent requests
let store = LimitStore::new(InMemory::new(), 20);

Implementations
