This library provides helper to convert uint256 chainid provided by block.chainid to uint32 chainid used across this Data Index implementation

error UnsupportedChain(uint256 chainId)

Error thrown when chainid is not supported

error UnexpectedChain(uint32 expected, uint32 requested)

Error thrown when chainid is not the current chain

error DifferentChainExpected(uint256 chainId)

Error thrown when chainid is not the expected chain

function chainid() internal view returns (uint32)

Converts block.chainid to uint32 chainid

Name	Type	Description

function requireCurrentChain(uint32 chainId) internal view

Requires current chain to be the same as requested

Name	Type	Description
chainId	uint32	Requested chain ID

function requireNotCurrentChain(uint32 chainId) internal view

Requires current chain to be different than requested
