Expand description

Typed Candid calls with caller-selected reply limits and contextual failures.

Pass Principal::anonymous() explicitly for anonymous access. Every call requires explicit DecodeLimits; these bound reply decoding, not PocketIC transport duration or canister execution.

Required Methods§

Source

fn update_candid<T, A>( &self, canister_id: Principal, caller: Principal, method: &str, args: A, limits: DecodeLimits, ) -> Result<T, CandidCallError>
where T: CandidType + DeserializeOwned, A: ArgumentEncoder,

Encode and execute an update call as an explicit caller.

Source

fn query_candid<T, A>( &self, canister_id: Principal, caller: Principal, method: &str, args: A, limits: DecodeLimits, ) -> Result<T, CandidCallError>
where T: CandidType + DeserializeOwned, A: ArgumentEncoder,

Encode and execute a query call as an explicit caller.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
