Module mutation 

Mutation types for CQL write operations

Represents INSERT, UPDATE, DELETE operations as structured mutations. Supports cell-level operations with timestamps and TTL.

This module implements the core data types for M5 write support:

• Mutation: Represents a write operation (INSERT, UPDATE, DELETE)
• DecoratedKey: Token + raw key bytes for partition ordering
• PartitionKey: Multi-column partition key with schema-aware encoding
• ClusteringKey: Multi-column clustering key with ASC/DESC ordering
• CellOperation: Cell-level write/delete operations

Structs

ClusteringKey

Clustering key with multi-column support

DecoratedKey

Decorated key: Murmur3 token + raw partition key bytes

Mutation

A mutation represents a write operation (INSERT, UPDATE, DELETE)

PartitionKey

PartitionTombstone

Partition tombstone for deleting entire partition

RangeTombstone

Range tombstone for deleting a range of clustering keys

TableId

Table identifier (keyspace + table name)

Enums

CellOperation

Operations that can be applied to individual cells within a row.

ClusteringBound

Clustering key bound for range tombstones
