# Struct PrivateCallData

Module: `noir_aztec::protocol::abis::private_kernel::private_call_data`

```rust
pub struct PrivateCallData {
    pub public_inputs: PrivateCircuitPublicInputs,
    pub vk: MegaAppVerificationKey,
    pub verification_key_hints: PrivateVerificationKeyHints,
}
```

## Fields

```rust
public_inputs: PrivateCircuitPublicInputs
```

```rust
vk: MegaAppVerificationKey
```

```rust
verification_key_hints: PrivateVerificationKeyHints
```

## Implementations

```rust
impl PrivateCallData
```

```rust
pub fn verify(self, is_first_function_call: bool)
```

Verifies the proof against the verification key and public inputs. The vk hash is also checked in the backend to match the key.
