Crate cobble_table 

Typed table schemas, codecs, and runtime access for Cobble.

cobble-table is independent from cobble-data-structure: table rows use a versioned cross-language codec, while specialized structures such as lists and priority queues keep their existing APIs and storage semantics.

Modules

catalog

snapshot

In-process coordination for table shard snapshots.

Structs

BucketHash

Stable bucket assignment for encoded bucket-key prefixes.

DataField

Named field in a top-level table row or nested struct.

ExtensionType

Provider-defined semantics with a portable physical fallback.

FieldId

Stable identity of a field within a table schema.

KeyCodec

Ordered, schema-directed composite-key codec.

LogicalType

Cross-language logical type, including nullability at every nesting level.

ProjectedTableScan

Iterator over projected typed rows from a bucket-scoped scan.

ReadOnlyTable

Typed read-only access to one table in a fixed shard snapshot.

ReadOnlyTableBuilder

Builder for a typed table over one shard snapshot.

Table

Typed access to one table-backed Cobble column family.

TableKey

A validated and encoded primary key for a table.

TableKeyBuilder

Incrementally builds one table primary key in schema order.

TableProjection

A reusable typed projection over one table or fixed snapshot table.

TableReader

A typed global snapshot read proxy.

TableReaderBuilder

Builder for a global typed reader from a fixed or current snapshot selection.

TableScan

Iterator over typed rows from a bucket-scoped table scan.

TableScanPlan

A serializable, fixed global-snapshot scan plan for one typed table.

TableScanSplit

A serializable full-table scan assignment for one shard snapshot.

TableScanSplitScanner

Typed iterator over every row assigned to one table scan split.

TableScanSplitScannerBuilder

Builder for one worker-local typed scan split scanner.

TableSchema

User-visible semantic schema of a table.

TableSchemaBuilder

Builder for a fresh table schema with generated, deterministic field ids.

TableWriteBuilder

Builds a portable writer initialization plan from one catalog table definition.

TableWritePlan

Serializable, catalog-independent initialization for one table writer shard.

TableWriterBuilder

Builder for a standalone writable typed table shard.

ValueCodec

Schema-directed value codec. encode_into appends to caller-owned memory.

Enums

LogicalTypeKind

Shape and parameters of a logical type.

SchemaChange

A top-level table schema edit addressed by its current field name.

TableError

TimestampKind

Timestamp semantic kind. Both kinds share the same physical encoding.

Value

Schema-directed dynamic value used by the cobble-table-v1 codec.

Functions

register_schema_transforms

Install Table’s built-in transforms before opening a core builder or starting a compactor.
