Module mem_vfs 

Memory VFS, used as the default VFS

use sqlite_wasm_rs as ffi;

fn open_db() {
    // open with memory vfs
    let mut db = std::ptr::null_mut();
    let ret = unsafe {
        ffi::sqlite3_open_v2(
            c"mem.db".as_ptr().cast(),
            &mut db as *mut _,
            ffi::SQLITE_OPEN_READWRITE | ffi::SQLITE_OPEN_CREATE,
            std::ptr::null()
        )
    };
    assert_eq!(ffi::SQLITE_OK, ret);
}

Data is stored in memory, this is the default vfs, and reading and writing are very fast, after all, in memory.

Refresh the page and data will be lost, and you also need to pay attention to the memory size limit of the browser page.
