BE-522: HashQL: Expand stdlib type system with temporal types by indietyp · Pull Request #8674 · hashintel/hash

indietyp · 2026-04-29T14:05:41Z

🌟 What is the purpose of this PR?

This PR expands the HashQL standard library's temporal type system and refactors how standard library types are defined and exposed. The QueryTemporalAxes type, previously a stub in the graph module, is replaced with a fully-specified temporal module containing a rich set of temporal bound and interval types (Timestamp, TemporalBound, Interval, LeftClosedTemporalInterval, RightBoundedTemporalInterval, PinnedTransactionTimeTemporalAxes, PinnedDecisionTimeTemporalAxes, QueryTemporalAxes, etc.). Entity types in the knowledge graph are updated to use real temporal metadata (using LeftClosedTemporalInterval) instead of opaque Unknown wrappers.

Alongside this, type construction logic is extracted into public types submodules for each standard library module, enabling external consumers to construct monomorphized type instances without going through the full module registration machinery. Several modules are made pub to support this. The ScratchPool allocator is introduced for multi-threaded bump allocation, and FromIn<&str, A> for Rc<str, A> is implemented. The RuntimeRepr symbol representation is refactored to use extern "C" unsized types and raw pointer field access to avoid provenance issues.

🔍 What does this change?

Introduces graph::temporal as a new standard library module with a full set of temporal types: Timestamp, DecisionTime, TransactionTime, UnboundedTemporalBound, InclusiveTemporalBound, ExclusiveTemporalBound, TemporalBound, FiniteTemporalBound, OpenTemporalBound, Interval, LeftClosedTemporalInterval, RightBoundedTemporalInterval, PinnedTransactionTimeTemporalAxes, PinnedDecisionTimeTemporalAxes, and QueryTemporalAxes.
Removes the stub QueryTemporalAxes (previously an empty opaque struct) from graph::Graph and moves it to the new temporal module.
Updates entity knowledge types to depend on graph::temporal::Temporal and use LeftClosedTemporalInterval for TemporalMetadata instead of an opaque Unknown wrapper.
Extracts type construction into public types submodules for core::option, core::url, core::uuid, graph::temporal, graph::types::ontology, graph::types::principal::actor_group, graph::types::principal::actor_group::web, and graph::types::knowledge::entity, each accepting optional dependency structs for injection.
Makes std_lib, std_lib::core, std_lib::graph, graph::types, graph::types::knowledge, graph::types::ontology, graph::types::principal, graph::types::principal::actor_group, graph::types::principal::actor_group::web, graph::temporal, module::std_lib, and module::std_lib::core::option/url/uuid public.
Adds ScratchPool and ScratchPoolGuard to the heap module, providing a Sync-capable pool of bump allocators backed by bump_scope::BumpPool.
Implements FromIn<&str, A> for Rc<str, A> with tests covering unicode, empty strings, and clone sharing.
Refactors RuntimeRepr to use an extern "C" unsized Unsize type and raw pointer field access (&raw const/mut) to avoid provenance narrowing issues, replacing str_from_raw_parts with str::from_utf8_unchecked and get_mut_unchecked/extern_types nightly features.
Migrates string literals used as symbol names and type paths to sym:: constants throughout, eliminating most heap.intern_symbol("...") calls.
Adds many new entries to the sym symbol table, including type names, field names, and fully-qualified path symbols for all new and existing types.

🛡 What tests cover this?

New unit tests for FromIn<&str, A> for Rc<str, A>: basic conversion, unicode, empty string, and clone pointer equality.
Existing standard library module integration tests cover the updated type definitions.

❓ How to test this?

Run cargo test -p hashql-core and confirm all tests pass.
Verify that the temporal module types are accessible and correctly structured via the standard library manifest.

PR Summary

Medium Risk
Touches core type definitions and symbol memory representation, including new unsafe pointer/provenance handling, so regressions could affect type checking and symbol interning. Changes are well-scoped but impact foundational libraries used broadly across HashQL.

Overview
Expands HashQL’s stdlib type surface, introducing a new ::graph::temporal module that replaces the old stub QueryTemporalAxes and defines concrete timestamp/bound/interval/axes types used throughout graph queries.

Refactors stdlib type construction by extracting reusable types helper modules (e.g. core::option/url/uuid, graph::types::*, graph::temporal) and making several stdlib modules public, enabling external callers to build monomorphized types without full module registration.

Updates graph/entity types and tests to use the new temporal metadata structures (e.g. RecordId, TemporalMetadata, LeftClosedTemporalInterval) and adjusts many UI snapshot expectations accordingly.

Heap/runtime improvements add a thread-shareable bump allocator pool (ScratchPool) and allocator-aware Rc<str> conversion, while tightening symbol runtime representation (RuntimeRepr) to avoid provenance UB via a new layout and raw-pointer access patterns.
