Pull.Error

Extracts the error type from a Pull type, excluding Done errors.

When to use

Use to derive only the ordinary failure type from a Pull when declaring wrappers or APIs that handle completion separately.

See

• Success for extracting the pulled value type instead
• Leftover for extracting the completion leftover type
• Services for extracting the required services type instead
• ExcludeDone for excluding Cause.Done from an error union

Signature

type Error<P> = P extends Effect<infer _A, infer _E, infer _R> ? _E extends Cause.Done<infer _L> ? never : _E
  : never
