pub fn substitute_params(stmt: &mut Statement, params: &[Value]) -> Result<()>Expand description
Substitutes every ?N placeholder in stmt with the matching value
from params. Mutates the AST in place — callers should clone first
if they want the original back.
Errors if the AST references a placeholder index outside params,
or if a non-canonical placeholder form (:name, $1) is encountered.
