Struct sqlite::Connection

pub struct Connection { /* fields omitted */ }

A database connection.

Methods

impl Connection

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

Open a connection to a new or existing database.

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<'l, T: AsRef<str>>(     &'l self,     statement: T ) -> Result<Statement<'l>>

Create a prepared statement.

pub fn set_busy_handler<F>(&mut self, callback: F) -> Result<()> where     F: FnMut(usize) -> bool + Send + 'static,

Set a callback for handling busy events.

The callback is triggered when the database cannot perform an operation due to processing of some other request. If the callback returns true, the operation will be repeated.

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 remove_busy_handler(&mut self) -> Result<()>

Remove the callback handling busy events.

pub fn as_raw(&self) -> *mut sqlite3

Return the raw pointer.
