No Types

-type attributes in header files should be avoided.

Quick fix

Move the -type next to the module/function it pertains to.

Rationale

Placing -type attributes in header files (.hrl) can lead to inconsistencies and maintenance issues, particularly when the same header is included in multiple modules. Keeping -type declarations within implementation (.erl) files improves maintainability by localizing type definitions to where they are used and owned. When combined with -export_type(_), this also leverages module-based namespacing, making type usage more explicit and reducing the risk of name clashes.

Options

• None.

Example configuration

{elvis_style, no_types, #{}}
