Struct RawSql 

pub struct RawSql<T> {
    pub where_clause: (Vec<String>, Vec<Param>),
    pub order_clause: Vec<String>,
    pub limit_clause: Option<[u64; 2]>,
    /* private fields */
}

Available on crate feature utils only.

Intermediate SQL representation passed through the decorator chain and filled layer by layer.

Received by Query::query_with_context(); filters append WHERE conditions via BaseFilter::update_sql(); Paginated sets limit_clause; Sorted appends to order_clause. Finally assembled into a complete SQL string by RawSql::build_sql().

Fields

where_clause: (Vec<String>, Vec<Param>)

WHERE clause: (list of condition strings, list of bound parameters), joined with AND.

order_clause: Vec<String>

ORDER BY expressions accumulated in append order.

limit_clause: Option<[u64; 2]>

[limit, offset] corresponding to LIMIT ? OFFSET ?. None means no pagination.
