Struct butane::db::sqlite::SQLiteConnection

pub struct SQLiteConnection { /* private fields */ }

SQLite database connection.

Trait Implementations

impl BackendConnection for SQLiteConnection

fn transaction(&mut self) -> Result<Transaction<'_>, Error>

Begin a database transaction. The transaction object must be used in place of this connection until it is committed and aborted.

fn backend(&self) -> Box<dyn Backend + 'static, Global>

Retrieve the backend backend this connection

fn backend_name(&self) -> &'static str

fn is_closed(&self) -> bool

Tests if the connection has been closed. Backends which do not support this check should return false.

impl ConnectionMethods for SQLiteConnection

fn execute(&self, sql: &str) -> Result<(), Error>

fn query<'a, 'c, 'b>( &'c self, table: &str, columns: &'b [Column], expr: Option<BoolExpr>, limit: Option<i32>, offset: Option<i32>, sort: Option<&[Order]> ) -> Result<Box<dyn BackendRows + 'a, Global>, Error>where 'c: 'a,

fn insert_returning_pk( &self, table: &str, columns: &[Column], pkcol: &Column, values: &[SqlValRef<'_>] ) -> Result<SqlVal, Error>

fn insert_only( &self, table: &str, columns: &[Column], values: &[SqlValRef<'_>] ) -> Result<(), Error>

Like insert_returning_pk but with no return value

fn insert_or_replace( &self, table: &str, columns: &[Column], pkcol: &Column, values: &[SqlValRef<'_>] ) -> Result<(), Error>

Insert unless there’s a conflict on the primary key column, in which case update

fn update( &self, table: &str, pkcol: Column, pk: SqlValRef<'_>, columns: &[Column], values: &[SqlValRef<'_>] ) -> Result<(), Error>

fn delete_where(&self, table: &str, expr: BoolExpr) -> Result<usize, Error>

fn has_table(&self, table: &str) -> Result<bool, Error>

Tests if a table exists in the database.

fn delete( &self, table: &str, pkcol: &'static str, pk: SqlVal ) -> Result<(), Error>

impl Debug for SQLiteConnection

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
