Expand description

Rusqlite is an ergonomic wrapper for using SQLite from Rust.

Historically, the API was based on the one from rust-postgres. However, the two have diverged in many ways, and no compatibility between the two is intended.

use rusqlite::{params, Connection, Result};

struct Person {
    id: i32,
    name: String,
    data: Option<Vec<u8>>,

fn main() -> Result<()> {
    let conn = Connection::open_in_memory()?;

        "CREATE TABLE person (
            id   INTEGER PRIMARY KEY,
            name TEXT NOT NULL,
            data BLOB
        (), // empty list of parameters.
    let me = Person {
        id: 0,
        name: "Steven".to_string(),
        data: None,
        "INSERT INTO person (name, data) VALUES (?1, ?2)",
        (&me.name, &me.data),

    let mut stmt = conn.prepare("SELECT id, name, data FROM person")?;
    let person_iter = stmt.query_map([], |row| {
        Ok(Person {
            id: row.get(0)?,
            name: row.get(1)?,
            data: row.get(2)?,

    for person in person_iter {
        println!("Found person {:?}", person.unwrap());

Online SQLite backup API.


Incremental BLOB I/O.

Configure database connections


Create or redefine SQL functions.


Commit, Data Change and Rollback Notification Callbacks


Run-Time Limits


Tracing and profiling functions. Error and warning log.

Traits dealing with SQLite data types.


Create virtual tables.


A macro making it more convenient to pass lists of named parameters as a &[(&str, &dyn ToSql)].

A macro making it more convenient to longer lists of parameters as a &[&dyn ToSql].


An iterator over the mapped resulting rows of a query, with an Error type unifying with Error.

Batch iterator

Cacheable statement.

Information about a column of a SQLite query.

A connection to a SQLite database.

Allows interrupting a long-running computation.


RAII guard temporarily enabling SQLite extensions to be loaded.

F is used to transform the streaming iterator into a fallible iterator.

An iterator over the mapped resulting rows of a query.

Flags for opening SQLite database connections. See sqlite3_open_v2 for details.

Adapter type which allows any iterator over ToSql values to implement Params.

A single result row of a query.

An handle for the resulting rows of a query.

Represents a savepoint on a database connection.

A prepared statement.

Represents a transaction on a database connection.


Name for a database within a SQLite connection.

Options for how a Transaction or Savepoint should behave when it is dropped.

Enum listing possible errors from rusqlite.

Error Codes

Prepared statement status counters.

Options for transaction behavior. See BEGIN TRANSACTION for details.



To be used when your statement has no parameter.


Trait used for sets of parameter passed into SQL statements/queries.

A trait implemented by types that can index into columns of a row.

A trait for types that can be converted into SQLite values. Returns Error::ToSqlConversionFailure if the conversion fails.


rusqlite’s check for a safe SQLite threading mode requires SQLite 3.7.0 or later. If you are running against a SQLite older than that, rusqlite attempts to ensure safety by performing configuration and initialization of SQLite itself the first time you attempt to open a connection. By default, rusqlite panics if that initialization fails, since that could mean SQLite has been initialized in single-thread mode.

Constructor function for a ParamsFromIter. See its documentation for more.

Returns the SQLite version as a string; e.g., "3.16.2" for version 3.16.2.

Returns the SQLite version as an integer; e.g., 3016002 for version 3.16.2.

Type Definitions

A typedef of the result returned by many methods.
