resource_ids

Mirrors src/shopify/resource-ids.ts.

Two ordering helpers that several domain serializers reach for:

compare_shopify_resource_ids — sort GIDs (gid://shopify/X/123) numerically by the trailing integer when both ends parse, falling back to lexicographic compare.
compare_nullable_strings — sort with explicit Some/None nullable handling: None sorts last, otherwise lexicographic.

Both return the conventional Lt/Eq/Gt instead of TS’s signed integer; callers pair with list.sort directly.

Values

compare_nullable_strings

pub fn compare_nullable_strings(
  left: option.Option(String),
  right: option.Option(String),
) -> order.Order

Compare two Option(String) values: None sorts after Some(_); two Some(_) values compare lexicographically.

compare_shopify_resource_ids

pub fn compare_shopify_resource_ids(
  left: String,
  right: String,
) -> order.Order

Compare two Shopify GID strings. Tries to extract the trailing integer (gid://shopify/Foo/123 → 123); when both sides parse, compares numerically. Falls back to lexicographic compare.
