Main diamond proxy contract implementing the EIP-2535 Diamond Standard

*This contract serves as the main proxy that delegates calls to different facets. It combines the functionality of diamond cutting (adding/removing/replacing facets), diamond loupe (introspection), and proxy delegation. Key Features:

• Modular architecture allowing unlimited contract size through facets

• Upgradeable functionality via diamond cuts

• Introspection capabilities via diamond loupe

• Gas-efficient function delegation*

Functions

constructor

Diamond constructor that initializes the diamond with base facets

Uses initializer modifier to prevent re-initialization

constructor(InitParams memory initDiamondCut) initializer;

Parameters

Name	Type	Description
initDiamondCut	InitParams	Initial diamond configuration including base facets

_implementation

Internal function to get the implementation address for a function call

Overrides Proxy._implementation() to use diamond storage for function routing

Note: throws: Diamond_UnsupportedFunction if no facet implements the function

function _implementation() internal view override returns (address facet);

Returns

Name	Type	Description
facet	address	The address of the facet that implements the called function

Structs

InitParams

Initialization parameters for diamond deployment

struct InitParams {
    FacetCut[] baseFacets;
    address init;
    bytes initData;
}

Properties

Name	Type	Description
baseFacets	FacetCut[]	Array of initial facets to add during deployment
init	address	Address of initialization contract (can be zero)
initData	bytes	Calldata for initialization function (can be empty)
