Implementations

impl Conn

pub fn new( ctx: *mut c_void, prepare_stmt: unsafe extern "C" fn(api: *mut Conn, sql: *const c_char) -> *mut Stmt, exec_fn: unsafe extern "C" fn(ctx: *mut Conn, sql: *const c_char, args: *mut Value, arg_count: i32, last_insert_rowid: *mut i64) -> ResultCode, close: unsafe extern "C" fn(ctx: *mut c_void), ) -> Self

pub unsafe fn from_ptr(ptr: *mut Conn) -> ExtResult<&'static mut Self>

Safety

Dereferences a null pointer with a null check

pub fn close(&mut self)

pub fn execute(&self, sql: &str, args: &[Value]) -> ExtResult<Option<usize>>

execute a SQL statement with the given arguments. optionally returns the last inserted rowid for the query

pub fn prepare_stmt(&self, sql: &str) -> *mut Stmt
