Trait ic_kit::CallHandler

pub trait CallHandler {
    fn accept(&self, canister_id: &Principal, method: &str) -> bool;
    fn perform(
        &self,
        caller: &Principal,
        cycles: u64,
        canister_id: &Principal,
        method: &str,
        args_raw: &Vec<u8>,
        ctx: Option<&mut MockContext>
    ) -> (CallResult<Vec<u8>>, u64);
}

Anything that could be used to simulate a inter-canister call.

Required Methods

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.
