Operable

Granular operator permissions with support for global and per-function operators.

Storage

crane.access.operable

Layers

• OperableRepo — mappings for operators and function-specific operators; guard _onlyOperator.
• OperableTarget
• OperableFacet
• OperableModifiers

Usage

Contracts inherit OperableModifiers to obtain the onlyOperator modifier.

Inside Repos and Targets, call OperableRepo._onlyOperator() directly for internal enforcement.

Function Operators

An address can be granted operator rights for a specific selector via setFunctionOperator. The guard checks both global isOperator and the per-selector mapping before reverting.

This enables least-privilege operator roles without deploying separate role contracts for every function.
