Trait Implementations

impl CallHandler for Canister

fn accept(&self, canister_id: &Principal, method: &str) -> bool

Whatever the handler can handle the given call or not, if this method returns false, we skip this handler and try to find the next handler that can handle the call.

fn perform( &self, caller: &Principal, cycles: u64, canister_id: &Principal, method: &str, args_raw: &Vec<u8>, ctx: Option<&mut MockContext>, ) -> (CallResult<Vec<u8>>, u64)

Perform the call using this handler. Only called if accept() first returned true.
