IC_Utils

Designed for rapid iteration in IC Canister development projects.

IcContext

IcContext provides the context for ic canister object invocation, which is used to store the object type and facilitate the user to store and call the object data in canister.

let tll = ic_utils::get_mut::<VecDeque<SwapOrder>>();

In this example, an empty VecDeque of type VecDeque is returned if no object of type VecDeque exists in the context, or a stored object if one exists. The returned object is actually a mutable reference, and any user edits to the reference will modify the object.
