### Public Functions

### void cass_index_meta_name(const [CassIndexMeta](#_CPPv413CassIndexMeta) \*index_meta, const char \*\*name, size_t \*name_length)

Gets the name of the index.

**Warning:** This function is not yet implemented.

* **Parameters:**
  * **index_meta** – **[in]** 
  * **name** – **[out]** 
  * **name_length** – **[out]** 

### [CassIndexType](#_CPPv4N13CassIndexMeta13CassIndexTypeE) cass_index_meta_type(const [CassIndexMeta](#_CPPv413CassIndexMeta) \*index_meta)

Gets the type of the index.

**Warning:** This function is not yet implemented.

* **Parameters:**
  **index_meta** – **[in]** 
* **Returns:**
  The index’s type. 

### void cass_index_meta_target(const [CassIndexMeta](#_CPPv413CassIndexMeta) \*index_meta, const char \*\*target, size_t \*target_length)

Gets the target of the index.

**Warning:** This function is not yet implemented.

* **Parameters:**

### const [CassValue](https://cpp-rs-driver.docs.scylladb.com/v1.1.0/api/struct.CassValue.md#_CPPv49CassValue) \*cass_index_meta_options(const [CassIndexMeta](#_CPPv413CassIndexMeta) \*index_meta)

Gets the options of the index.

**Warning:** This function is not yet implemented.

* **Parameters:**
  **index_meta** – **[in]** 
* **Returns:**
  The index’s options. 

### const [CassValue](https://cpp-rs-driver.docs.scylladb.com/v1.1.0/api/struct.CassValue.md#_CPPv49CassValue) \*cass_index_meta_field_by_name(const [CassIndexMeta](#_CPPv413CassIndexMeta) \*index_meta, const char \*name)

Gets a metadata field for the provided name. Metadata fields allow direct access to the index data found in the underlying “indexes” metadata table.

**Warning:** This function is not yet implemented.

* **Parameters:**
  * **index_meta** – **[in]** 
  * **name** – **[in]** 
* **Returns:**
  A metadata field value. NULL if the field does not exist. 

### const [CassValue](https://cpp-rs-driver.docs.scylladb.com/v1.1.0/api/struct.CassValue.md#_CPPv49CassValue) \*cass_index_meta_field_by_name_n(const [CassIndexMeta](#_CPPv413CassIndexMeta) \*index_meta, const char \*name, size_t name_length)

Same as [cass_index_meta_field_by_name()](#struct_cass_index_meta_1af535acba55cfe29f30ebb0db8a5fa80a), but with lengths for string parameters.

**Warning:** This function is not yet implemented.
