Function expr_as_usize_literal 

Source 
pub fn expr_as_usize_literal(
    expr: &Expr,
) -> Result<usize, InvalidRowBoundLiteral>
Expand description

Resolve an Expr::Value into a usize row bound. Thin wrapper that unpacks the Expr → Value layer so callers reading LIMIT/OFFSET/FETCH clauses don’t each re-write the unpack. A non-Expr::Value expression (a column reference, a function call, an arithmetic expression) is not a literal the planner can read — it fails with the expression’s Display text as raw.
