SQLite

The package provides an interface to SQLite.
Example
Open a connection, create a table, and insert some rows:
let connection = sqlite::open(":memory:").unwrap();
connection
.execute(
"
CREATE TABLE users (name TEXT, age INTEGER);
INSERT INTO users VALUES ('Alice', 42);
INSERT INTO users VALUES ('Bob', 69);
",
)
.unwrap();
Select some rows and process them one by one as plain text:
connection
.iterate("SELECT * FROM users WHERE age > 50", |pairs| {
for &(column, value) in pairs.iter() {
println!("{} = {}", column, value.unwrap());
}
true
})
.unwrap();
The same query using a prepared statement, which is much more efficient than the previous technique:
use sqlite::State;
let mut statement = connection
.prepare("SELECT * FROM users WHERE age > ?")
.unwrap();
statement.bind(1, 50).unwrap();
while let State::Row = statement.next().unwrap() {
println!("name = {}", statement.read::<String>(0).unwrap());
println!("age = {}", statement.read::<i64>(1).unwrap());
}
The same query using a cursor, which is a wrapper around a prepared statement providing the concept of row and featuring all-at-once binding:
use sqlite::Value;
let mut cursor = connection
.prepare("SELECT * FROM users WHERE age > ?")
.unwrap()
.cursor();
cursor.bind(&[Value::Integer(50)]).unwrap();
while let Some(row) = cursor.next().unwrap() {
println!("name = {}", row[0].as_string().unwrap());
println!("age = {}", row[1].as_integer().unwrap());
}
