Effect.Error

Extracts the error type from an Effect.

When to use

Use to derive the error type from an existing Effect type when declaring helper types, wrappers, or APIs that preserve the effect’s failure channel.

Details

Non-Effect inputs resolve to never.

See

• Success for extracting the success value type instead
• Services for extracting the required services type instead
