Expand description

Invokes a contract message and returns its result.

§Note

This will call into the latest version of the host function which allows setting new weight and storage limit parameters.

This is a low level way to evaluate another smart contract. Prefer to use the ink! guided and type safe approach to using this.

§Errors

  • If the called account does not exist.
  • If the called account is not a contract.
  • If arguments passed to the called contract message are invalid.
  • If the called contract execution has trapped.
  • If the called contract ran out of gas, proof size, or storage deposit upon execution.
  • If the returned value failed to decode properly.
