E1007: expected type or pattern binding

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

Explanation

This parser code is reused in several places: type positions, type-argument lists, and result-pattern bindings. The parser needed either a valid type syntax or a valid identifier/_ binding, depending on the message at the error site.

Common causes

• leaving a type annotation incomplete
• writing an empty generic type-argument list
• using an invalid token inside ok(...) or err(...) patterns

Canonical fixes

• complete the type syntax

Before:

value: = 1

After:

value: Int = 1

• bind result patterns with an identifier or _

Before:

match result
    ok(1) => 1

After:

match result
    ok(value) => value

Code example

value: = 1
