S0035: ordered comparison requires Int, Float, or Char

Generated from rellum-diagnostics/src/db.rs.

Explanation

The <, >, <=, and >= operators require a type with built-in ordering. In this compiler version, only Int, Float, and Char satisfy that operation; String ordering is intentionally not part of the ord model.

Common causes

• comparing arrays, records, enums, tuples, functions, or Bool values with ordered operators
• using ordered comparison on String values
• expecting lexicographic ordering without writing it explicitly

Canonical fixes

• compare an ordered scalar or projection

Before:

is_shorter = left < right

After:

is_shorter = len(left) < len(right)

• write an explicit comparison helper for domain-specific ordering

Code example

is_shorter = left < right
