ERC20MetadataStorage

Library for managing storage of ERC20 token metadata in a diamond pattern implementation. This library uses the diamond storage pattern to maintain upgrade safety by storing metadata in a specific storage slot determined by a unique hash.

Layout

Storage layout structure for ERC20 metadata

Parameters

Name	Type	Description

struct Layout {
  string name;
  string symbol;
  uint8 decimals;
}

STORAGE_SLOT

bytes32 STORAGE_SLOT

Unique storage slot for ERC20 metadata The slot is determined by hashing a unique string to prevent storage collision with other diamond facets. This follows the diamond storage pattern.

layout

function layout() internal pure returns (struct ERC20MetadataStorage.Layout l)

Provides access to the storage layout

Return Values

Name	Type	Description
l	struct ERC20MetadataStorage.Layout	The storage layout struct pointing to the correct storage slot
