Required Methods§

Source

fn call<ResultType>( &self, canister_id: Principal, call_mode: CallMode, method: &str, args: Result<Vec<u8>, Error>, ) -> CallBuilder<ResultType, Self::Provider>
where ResultType: for<'a> Deserialize<'a> + CandidType,

Initiate a call to a canister method.

§Parameters
  • canister_id: The target canister’s principal.
  • call_mode: Whether this is a query or update.
  • method: Method name to call.
  • args: Encoded Candid arguments or error.
§Returns

A configured CallBuilder to execute the call.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
