Trait pallet_contracts::debug::CallInterceptor

pub trait CallInterceptor<T: Config> {
    // Required method
    fn intercept_call(
        contract_address: &T::AccountId,
        entry_point: &ExportedFunction,
        input_data: &[u8],
    ) -> Option<ExecResult>;
}

Provides an interface for intercepting contract calls.

Required Methods

fn intercept_call( contract_address: &T::AccountId, entry_point: &ExportedFunction, input_data: &[u8], ) -> Option<ExecResult>

Allows to intercept contract calls and decide whether they should be executed or not. If the call is intercepted, the mocked result of the call is returned.

Arguments

• contract_address - The address of the contract that is about to be executed.
• entry_point - Describes whether the call is the constructor or a regular call.
• input_data - The raw input data of the call.

Expected behavior

This method should return:

• Some(ExecResult) - if the call should be intercepted and the mocked result of the call is returned.
• None - otherwise, i.e. the call should be executed normally.

Object Safety

This trait is not object safe.
