SqliteConnection

Struct SqliteConnection 

Source
pub struct SqliteConnection { /* private fields */ }
Expand description

A connection to a SQLite database.

This is a thread-safe wrapper around a SQLite database handle.

Implementations§

Source§

impl SqliteConnection

Source

pub fn open(config: &SqliteConfig) -> Result<Self, Error>

Open a new SQLite connection with the given configuration.

Source

pub fn open_memory() -> Result<Self, Error>

Open an in-memory database.

Source

pub fn open_file(path: impl Into<String>) -> Result<Self, Error>

Open a file-based database.

Source

pub fn path(&self) -> &str

Get the database path.

Source

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

Execute SQL directly without preparing (for DDL, etc.)

Source

pub fn backup_to_path(&self, dest_path: impl AsRef<str>) -> Result<(), Error>

Backup the current database to a destination path using the SQLite backup API.

This opens (or creates) the destination database and performs an online backup from this connection’s main database into the destination’s main database.

Source

pub fn backup_to_connection(&self, dest: &SqliteConnection) -> Result<(), Error>

Backup the current database to another open SQLite connection.

Source

pub fn last_insert_rowid(&self) -> i64

Get the last insert rowid.

Source

pub fn changes(&self) -> i32

Get the number of rows changed by the last statement.

Source

pub fn query_sync(&self, sql: &str, params: &[Value]) -> Result<Vec<Row>, Error>

Prepare and execute a query synchronously, returning all rows.

This is a blocking operation suitable for simple use cases. For async usage, use the Connection trait methods instead.

Source

pub fn execute_sync(&self, sql: &str, params: &[Value]) -> Result<u64, Error>

Prepare and execute a statement synchronously, returning rows affected.

This is a blocking operation suitable for simple use cases. For async usage, use the Connection trait methods instead.

Source§

impl SqliteConnection

Source

pub fn emit_busy_waiting(&self, _elapsed_secs: f64)

No-op when console feature is disabled.

Source

pub fn emit_checkpoint_progress(&self, _pages_done: u32, _pages_total: u32)

No-op when console feature is disabled.
