Crate memstead_schema 

Type definitions, schema loading, and mem-config validation for Memstead.

Schemas are first-class packages — named, versioned bundles of type definitions + relationship vocabulary + LLM-facing documentation. The engine holds a SchemaRegistry mapping (name, version) to Arc<Schema>. Each mem pins exactly one schema via MemConfig.schema: SchemaRef.

Modules

archive_provenance

Authoring-provenance payload carried inside a sealed .mem archive.

base_metadata

Metadata fields every entity carries regardless of type.

builtin_names

Name constants for the 10 built-in knowledge types shipped in the default schema. Kept as a module to catch typos at compile time.

builtins

Embedded builtin schemas, baked into the binary via include_dir!.

config

Mem configuration loading, validation, and top-level CRUD.

content_expr

Content expressions — the compiled half of the section-format vocabulary (agent-toolbox plan 08).

loader

Schema loader — reads on-disk schema directories (or in-memory YAML) into validated Schema values with edge_weights resolved.

manifest

Schema manifest (schema.yaml) — the outer envelope declaring a schema package: name, version, type list, relationship vocabulary, community defaults, and LLM-facing documentation.

meta_schema

Embedded JSON Schemas (the “meta-schemas”) for authoring validation.

schema

In-memory representation of a loaded schema.

source

Schema source-file collection for publishing mem archives.

types

Schema-as-artifact type format.

workspace_config

Cross-mem-link policy value parsing for .memstead/workspace.toml.

Structs

SchemaNameAmbiguous

Error returned by SchemaRegistry::resolve_by_name when a bare-name lookup matches multiple registered versions. Surfaced by the memstead_schema(name=...) discovery surface — callers must supply an exact <name>@<version> to disambiguate.

SchemaRegistry

Registry holding every loaded schema keyed by (name, version).

Enums

SchemaRegistryError

WorkspaceSchemaLoadError

Errors raised while scanning workspace-level or cache schema directories.

Functions

all_types

Every type in the built-in default schema, in declaration order.

type_by_name

Lookup by short type name against the built-in default schema.
