source · [−]pub struct ConnectionWithFullMutex(_);Expand description
A thread-safe database connection.
Methods from Deref<Target = Connection>
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 change_count(&self) -> usize
pub fn change_count(&self) -> usize
Return the number of rows inserted, updated, or deleted by the most recent INSERT, UPDATE, or DELETE statement.
sourcepub fn total_change_count(&self) -> usize
pub fn total_change_count(&self) -> usize
Return the total number of rows inserted, updated, and deleted by all INSERT, UPDATE, and DELETE statements since the connection was opened.
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.
