Macros

cost_return_on_error

Macro to achieve kind of what the ? operator does, but with CostContext on top.

cost_return_on_error_default

Macro to achieve kind of what the ? operator does, but with CostContext on top. The difference between this macro and cost_return_on_error is that it is intended to be used on Result rather than CostContext<Result<..>>, so no costs will be added except previously accumulated. The error case returns a default OperationCost.

cost_return_on_error_into

Macro to achieve kind of what the ? operator does, but with CostContext on top.

cost_return_on_error_into_default

Macro to achieve kind of what the ? operator does, but with CostContext on top. The difference between this macro and cost_return_on_error is that it is intended to be used on Result rather than CostContext<Result<..>>, so no costs will be added except previously accumulated. The error case returns a default OperationCost.

cost_return_on_error_into_no_add

Macro to achieve kind of what the ? operator does, but with CostContext on top. The difference between this macro and cost_return_on_error is that it is intended to be used on Result rather than CostContext<Result<..>>, so no costs will be added except previously accumulated.

cost_return_on_error_no_add

Macro to achieve kind of what the ? operator does, but with CostContext on top. The difference between this macro and cost_return_on_error is that it is intended to be used on Result rather than CostContext<Result<..>>, so no costs will be added except previously accumulated.
