Function json_gt 

pub fn json_gt<'a, L, R>(left: L, path: &'a str, value: R) -> SQLiteSQL<'a>
where
    L: ToSQL<'a, SQLiteValue<'a>>,
    R: Into<SQLiteValue<'a>> + ToSQL<'a, SQLiteValue<'a>>,

Create a JSON numeric greater-than condition

Example

let column = SQL::<SQLiteValue>::raw("metadata");
let condition = json_gt(column, "$.score", 85.0);
assert_eq!(condition.sql(), "CAST(json_extract( metadata , '$.score') AS NUMERIC) > ?");
