Struct Connection

pub struct Connection { /* private fields */ }

A database connection.

Implementations

impl Connection

pub fn open<T: AsRef<Path>>(path: T) -> Result<Connection>

Open a read-write connection to a new or existing database.

pub fn open_with_flags<T: AsRef<Path>>( path: T, flags: OpenFlags, ) -> Result<Connection>

Open a database connection with specific flags.

pub fn execute<T: AsRef<str>>(&self, statement: T) -> Result<()>

Execute a statement without processing the resulting rows if any.

pub fn iterate<T: AsRef<str>, F>(&self, statement: T, callback: F) -> Result<()>

where F: FnMut(&[(&str, Option<&str>)]) -> bool,

Execute a statement and process the resulting rows as plain text.

The callback is triggered for each row. If the callback returns false, no more rows will be processed. For large queries and non-string data types, prepared statement are highly preferable; see prepare.

pub fn prepare<T: AsRef<str>>(&self, statement: T) -> Result<Statement>

Create a prepared statement.

pub fn changes(&self) -> usize

Return the number of rows inserted, updated, or deleted by the most recent INSERT, UPDATE, or DELETE statement.

pub fn total_changes(&self) -> usize

Return the total number of rows inserted, updated, and deleted by all INSERT, UPDATE, and DELETE statements since the connection was opened.

pub fn set_busy_timeout(&mut self, milliseconds: usize) -> Result<()>

Set an implicit callback for handling busy events that tries to repeat rejected operations until a timeout expires.

pub fn as_raw(&self) -> u32

Return the raw pointer.
