pub struct Schema {

}

Fields

cookie: u32

The schema cookie is a 4-byte big-endian integer at offset 40 that is incremented whenever the database schema changes. A prepared statement is compiled against a specific version of the database schema. When the database schema changes, the statement must be reprepared. When a prepared statement runs, it first checks the schema cookie to ensure the value is the same as when the statement was prepared and if the schema cookie has changed, the statement either automatically reprepares and reruns or it aborts with an SQLITE_SCHEMA error.

format: SchemaFormat
