Struct PreparedStatement

pub struct PreparedStatement<T = Bound>(/* private fields */);

A statement that has been prepared against at least one Cassandra node. Instances of this class should not be created directly, but through Session.prepare().

Implementations

impl<T: Clone> PreparedStatement<T>

pub fn bind(&self) -> Statement<T>

Creates a bound statement from a pre-prepared statement.

pub fn session(&self) -> &Session<T>

Returns the session of which this prepared statement is bound to.

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

Gets the name of a parameter at the specified index.

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

Gets the data type of a parameter at the specified index.

Returns a reference to the data type of the parameter. Do not free this reference as it is bound to the lifetime of the prepared.

pub fn parameter_data_type_by_name(&self, name: &str) -> Option<ConstDataType>

Gets the data type of a parameter for the specified name.

Returns a reference to the data type of the parameter. Do not free this reference as it is bound to the lifetime of the prepared.
