@prisma/param-graph

This package is intended for Prisma's internal use.

Contains the ParamGraph types and utilities for schema-aware query parameterization in Prisma Client.

ParamGraph is a compact data structure generated from DMMF (Data Model Metadata Format) at client generation time. It enables precise, schema-driven parameterization of query values at runtime.

• InputEdge / OutputEdge - Edge types describing field capabilities
• EdgeFlag - Bit flags for input field capabilities
• ScalarMask - Bit mask for scalar type categories
• scalarTypeToMask - Maps DMMF scalar type names to mask values
• hasFlag / getScalarMask - Helper functions for edge inspection
