Struct PreparedStatement 

pub struct PreparedStatement { /* private fields */ }

A prepared statement for repeated execution.

Prepared statements are pre-compiled by the database, allowing efficient repeated execution with different parameter values. They also help prevent SQL injection since parameters are handled separately from the SQL text.

Implementations

impl PreparedStatement

pub fn new(id: u64, sql: String, param_count: usize) -> Self

Create a new prepared statement.

This is typically called by the driver, not by users directly.

pub fn with_columns( id: u64, sql: String, param_count: usize, columns: Vec<String>, ) -> Self

Create a prepared statement with column information.

pub const fn id(&self) -> u64

Get the statement ID.

pub fn sql(&self) -> &str

Get the original SQL text.

pub const fn param_count(&self) -> usize

Get the expected number of parameters.

pub fn columns(&self) -> Option<&[String]>

Get the column information, if available.

pub fn validate_params(&self, params: &[Value]) -> bool

Check if the provided parameters match the expected count.

Trait Implementations

impl Clone for PreparedStatement

fn clone(&self) -> PreparedStatement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PreparedStatement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
