Struct Limit 

pub struct Limit {
    pub count: Option<Expr>,
}

LIMIT n

The count is an expression, not a number: SQLite accepts an arbitrary expression there, and every dialect accepts a bound argument. limit(10) gives the literal LIMIT 10 because a number converts to Expr::Raw; limit(arg(10)) binds it instead. Narrowing that back down to a literal is a dialect mod’s job.

Fields

count: Option<Expr>

How many rows.
