S0034: arithmetic operator requires Int or Float

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

Explanation

The -, *, and / operators are numeric operations. Both operands must have the same numeric type, and Rellum does not implicitly convert other values into Int or Float.

Common causes

• subtracting, multiplying, or dividing Bool, Char, String, array, record, or enum values
• mixing Int and Float without an explicit conversion
• using arithmetic syntax where a domain-specific helper is needed

Canonical fixes

• use numeric operands of the same type

Before:

value = text - suffix

After:

value = count - offset

• convert values explicitly before arithmetic

Code example

value = text - suffix
