Crate rusqlite [−] [src]

Rusqlite is an ergonomic wrapper for using SQLite from Rust. It attempts to expose an interface similar to rust-postgres.

extern crate rusqlite;
extern crate time;

use time::Timespec;
use rusqlite::Connection;

#[derive(Debug)]
struct Person {
    id: i32,
    name: String,
    time_created: Timespec,
    data: Option<Vec<u8>>
}

fn main() {
    let conn = Connection::open_in_memory().unwrap();

    conn.execute("CREATE TABLE person (
                  id              INTEGER PRIMARY KEY,
                  name            TEXT NOT NULL,
                  time_created    TEXT NOT NULL,
                  data            BLOB
                  )", &[]).unwrap();
    let me = Person {
        id: 0,
        name: "Steven".to_string(),
        time_created: time::get_time(),
        data: None
    };
    conn.execute("INSERT INTO person (name, time_created, data)
                  VALUES (?1, ?2, ?3)",
                 &[&me.name, &me.time_created, &me.data]).unwrap();

    let mut stmt = conn.prepare("SELECT id, name, time_created, data FROM person").unwrap();
    let person_iter = stmt.query_map(&[], |row| {
        Person {
            id: row.get(0),
            name: row.get(1),
            time_created: row.get(2),
            data: row.get(3)
        }
    }).unwrap();

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

Modules

limits	Run-Time Limits
types	Traits dealing with SQLite data types.

Structs

AndThenRows	An iterator over the mapped resulting rows of a query, with an Error type unifying with Error.
CachedStatement	Cacheable statement.
Connection	A connection to a SQLite database.
MappedRows	An iterator over the mapped resulting rows of a query.
OpenFlags	Flags for opening SQLite database connections. See sqlite3_open_v2 for details.
Row	A single result row of a query.
Rows	An handle for the resulting rows of a query.
Savepoint	Represents a savepoint on a database connection.
Statement	A prepared statement.
Transaction	Represents a transaction on a database connection.

Enums

DatabaseName	Name for a database within a SQLite connection.
DropBehavior	Options for how a Transaction or Savepoint should behave when it is dropped.
Error	Enum listing possible errors from rusqlite.
ErrorCode	Error Codes
TransactionBehavior	Options for transaction behavior. See BEGIN TRANSACTION for details.

Traits

RowIndex

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

Functions

bypass_sqlite_initialization ^⚠	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.
bypass_sqlite_version_check ^⚠	rusqlite performs a one-time check that the runtime SQLite version is at least as new as the version of SQLite found when rusqlite was built. Bypassing this check may be dangerous; e.g., if you use features of SQLite that are not present in the runtime version. If you are sure the runtime version is compatible with the build-time version for your usage, you can bypass the version check by calling this function before your first connection attempt.
version	Returns the SQLite version as a string; e.g., `"3.16.2"` for version 3.16.2.
version_number	Returns the SQLite version as an integer; e.g., `3016002` for version 3.16.2.
