Struct PageCount 

pub struct PageCount;

Available on crate feature __sqlite-shared only.

PRAGMA page_count, the total number of pages in a database, read as an i64.

Multiply by the page size for the size the database accounts for.

use diesel::connection::SimpleConnection;
use diesel::sqlite::pragma::{PageCount, SchemaPragma};

let conn = &mut SqliteConnection::establish(":memory:").unwrap();
// An empty database occupies no pages until something is written.
assert_eq!(0, PageCount::get::<i64>(None, conn)?);
conn.batch_execute("CREATE TABLE items (id INTEGER PRIMARY KEY)")?;
assert!(PageCount::get::<i64>(None, conn)? > 0);
