S0011: tuple field access requires a tuple

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

Explanation

The .N tuple field syntax is positional access for tuple values. Named records use .field access, and arrays use [index], so .N is rejected for non-tuple values.

Common causes

• using .0 on an array or record
• using tuple field syntax on a scalar value
• expecting record fields to be addressed by position

Canonical fixes

• use .N only on a tuple

Before:

first = items.0

After:

first = (left, right).0

• use the record field name for records

Before:

x = point.0

After:

x = point.x

Code example

first = items.0
