ERC20MetadataInternal

_Provides the internal implementation for ERC20 metadata management. This contract handles the storage and modification of token metadata including name, symbol, and decimals. It uses a dedicated storage contract to maintain upgrade safety in diamond implementations.

This contract is meant to be inherited by other contracts that need to manage ERC20 metadata internally, providing a clean separation between storage access and external interfaces._

_name

function _name() internal view virtual returns (string)

Returns the name of the token

Reads the token name from the ERC20MetadataStorage layout

Return Values

Name	Type	Description
[0]	string	The name of the token as a string

_symbol

function _symbol() internal view virtual returns (string)

Returns the symbol of the token

Reads the token symbol from the ERC20MetadataStorage layout

Return Values

Name	Type	Description
[0]	string	The symbol of the token as a string

_decimals

function _decimals() internal view virtual returns (uint8)

Returns the number of decimals used for token display

Reads the decimals value from the ERC20MetadataStorage layout. The decimals value is used to determine how to interpret the token's raw numeric value. For example, if decimals is 2, a raw value of 100 should be displayed as 1.00

Return Values

Name	Type	Description
[0]	uint8	The number of decimals places for token display

_setName

function _setName(string name) internal virtual

Sets the name of the token

Updates the token name in the ERC20MetadataStorage layout

Parameters

Name	Type	Description
name	string	The new name to set for the token

_setSymbol

function _setSymbol(string symbol) internal virtual

Sets the symbol of the token

Updates the token symbol in the ERC20MetadataStorage layout

Parameters

Name	Type	Description
symbol	string	The new symbol to set for the token

_setDecimals

function _setDecimals(uint8 decimals) internal virtual

Sets the number of decimals for token display

Updates the decimals value in the ERC20MetadataStorage layout

Parameters

Name	Type	Description
decimals	uint8	The new number of decimals to use for token display
