Designed for rapid iteration in IC Canister development projects.
IcContext
provides a context for invoking IC canister objects, facilitating storage and retrieval of object data within the canister.
NatUtils
enables rapid generation and conversion of Nat types for natural numbers.
Guard
supports locking operations on canisters to prevent data reentry anomalies.
Throws
utility class handles exceptions, triggering panic for exceptional instances and returning data results for normal cases.
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 = context::get_mut::<VecDeque<SwapOrder>>();
In this example, an empty VecDeque of type VecDeque<SwapOrder> is returned if no object of type VecDeque<SwapOrder> 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.
nat_utils
is used for rapidly generating Nat types as natural numbers and performing mutual conversions between different types.
fstr_to_nat("3.1231313",1_000_000_000_000_000_000f64);
In this example, we are converting numeric characters of type 'str' into Nat numbers with 18-digit precision.
The tool supports locking operations requested to canister to prevent anomalies caused by data reentry.
//Add Exclusion Lock
let guard = CallerGuard::new(id().clone());
if guard.is_err() {
panic!("{}",guard.err().unwrap());
}
The throws utility class is used to handle exceptions when called, throwing panic when the received instance is an exception and returning data results when normal.
//Exception handling when creating a canister
let (cid, ) = throw(create_canister(CreateCanisterArgument {
settings: Some(CanisterSettings {
controllers: Some(vec![id()]),
compute_allocation: None,
memory_allocation: None,
freezing_threshold: None,
})
}, 500000000000).await.map_err(|e| "Create Pool failed:".to_string() + &*e.1));
Developers continue to enhance this toolchain to support a broader range of application scenarios and to accelerate development efficiency on the IC platform.
