A database connection.
Implementations
sourceimpl Connection
impl Connection
sourcepub fn open<T: AsRef<Path>>(path: T) -> Result<Connection>
pub fn open<T: AsRef<Path>>(path: T) -> Result<Connection>
Open a connection to a new or existing database.
sourcepub fn execute<T: AsRef<str>>(&self, statement: T) -> Result<()>
pub fn execute<T: AsRef<str>>(&self, statement: T) -> Result<()>
Execute a statement without processing the resulting rows if any.
sourcepub fn iterate<T: AsRef<str>, F>(&self, statement: T, callback: F) -> Result<()>where
F: FnMut(&[(&str, Option<&str>)]) -> bool,
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
.
sourcepub fn prepare<'l, T: AsRef<str>>(
&'l self,
statement: T
) -> Result<Statement<'l>>
pub fn prepare<'l, T: AsRef<str>>(
&'l self,
statement: T
) -> Result<Statement<'l>>
Create a prepared statement.
sourcepub fn set_busy_handler<F>(&mut self, callback: F) -> Result<()>where
F: FnMut(usize) -> bool + Send + 'static,
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.
sourcepub fn set_busy_timeout(&mut self, milliseconds: usize) -> Result<()>
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.
sourcepub fn remove_busy_handler(&mut self) -> Result<()>
pub fn remove_busy_handler(&mut self) -> Result<()>
Remove the callback handling busy events.
