Expand description
Foundational primitive types shared by every other crate in the workspace - the value enum, type enum, type
constraints, the source-fragment carrier used in diagnostics, the error and diagnostic machinery, and the parameter
binding shape used at the wire boundary. This crate is the bottom of the dependency graph; nothing here depends on
core or any other ReifyDB crate.
Anything that wants a stable representation of a column value, a typed identifier, a parameter list, or a
diagnostic anchor uses this crate. The reason it sits below core rather than inside it is to break what would
otherwise be a cycle: core itself needs values and diagnostics.
Invariant: types declared here are wire-stable and on-disk-stable. Adding a variant to Type or Value is a
workspace-wide change that requires bumping wire-format and storage encodings; rearranging the existing variants
silently corrupts persisted data and cross-version replication.
Modules§
- error
- Diagnostic and error machinery used by every other crate in the workspace. The
Errortype carries a structuredDiagnosticplus the source-fragment context needed to render a user-visible message that points at the offending span; the rendering, the serde shape, and the helper macros that simplify producing one all live here. - fragment
- params
- storage
- util
- Small dependency-free utilities used throughout the workspace: the bit-vector backing none-bitmaps and row
masks, the copy-on-write vector
CowVecthat the storage tier uses for delta lists, base58/base64/hex codecs, Unicode helpers, and float formatting that respects the workspace’s text rendering rules. - value
- Workspace-wide value system. Defines the
Valueenum every column carries, theTypeenum that classifies it, theConstraintfamily that narrows a type (max-bytes, precision-scale, optional), and the per-primitive representations - integers, unsigned integers, decimals, floats, blobs, booleans, temporals, UUIDs, JSON, identity ids, and row numbers - that those variants wrap.
