Expand description

Any cassandra datatype (const).

Implementations

source

impl ConstDataType

source

pub fn new_user_type(&self) -> UserType

Creates a new user defined type from existing data type.

source

pub fn get_type(&self) -> ValueType

Gets the value type of the specified data type.

source

pub fn sub_type_count(&self) -> usize

Gets the sub-data type count of a UDT (user defined type), tuple or collection.

Note: Only valid for UDT, tuple and collection data types.

source

pub fn sub_data_type(&self, index: usize) -> Option<ConstDataType>

Gets the sub-data type of a UDT (user defined type), tuple or collection at the specified index.

Note: Only valid for UDT, tuple and collection data types.

source

pub fn type_name(&self) -> Result<&str>

Returns the type name of the data type, if it’s a UDT.

source

pub fn keyspace(&self) -> Result<&str>

Returns the type name of the data type, if it’s a UDT.

source

pub fn sub_type_name(&self, index: usize) -> Result<&str>

Gets the sub-type name of a UDT (user defined type) at the specified index.

Note: Only valid for UDT data types.
