# Permissionable

The **Permissionable** component is primarily used to set permissions for authorized addresses to carry out specific actions.

By leveraging this component, developers can build applications where users maintain control over key functions while safely delegating specific tasks to other addresses. Permissioned addresses can also play a minimal role of guardians.

The full contract code of the `PermissionableComponent` can be found [**here**](https://github.com/horuslabsio/TBA/blob/v3/src/components/permissionable/permissionable.cairo)**.**

## Functions

### `_set_permission`

```rust
fn _set_permission(
    ref self: ComponentState<TContractState>,
    permissioned_addresses: Array<ContractAddress>,
    permissions: Array<bool>
);
```

This function assigns or revokes a specific permission to an address for a particular profile.

#### Parameters

| Name                     | Type                     | Description                                                                                                                   |
| ------------------------ | ------------------------ | ----------------------------------------------------------------------------------------------------------------------------- |
| `permissioned_addresses` | `Array<ContractAddress>` | An array of addresses that need permission updates. The length of this array must match the length of the `permissions` array |
| `permissions`            | `Array<bool>`            | A corresponding array of boolean values where `true` grants permission and `false` revokes.                                   |

### `_has_permission`

```rust
fn _has_permission(
    self: @ComponentState<TContractState>,
    owner: ContractAddress,
    permissioned_address: ContractAddress
) -> bool

```

This function checks whether a specific `permissioned_address` has been granted permission by the given account owner.

Parameters

| Name                   | Type              | Description                             |
| ---------------------- | ----------------- | --------------------------------------- |
| `owner`                | `ContractAddress` | An instance of the component.           |
| `permissioned_address` | `ContractAddress` | The interface ID to be checked against. |

#### Returns

`bool:`  returns `true` if the `permissioned_address` has been granted permission by the `owner`and `false` if the `permissioned_address` has no permission.
