[−][src]Struct cassandra_cpp::PreparedStatement

pub struct PreparedStatement(_);

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().

Methods

impl PreparedStatement
[src]

pub fn bind(&self) -> Statement
[src]

Creates a bound statement from a pre-prepared statement.

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

Gets the name of a parameter at the specified index.

pub fn parameter_data_type(&self, index: usize) -> ConstDataType
[src]

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) -> ConstDataType
[src]

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.
