Class: Block
provider.Block
This class is formatting the identifier of a block.
hex string and BigInt are detected as block hashes. identifier return { block_hash: hash }
decimal string and number are detected as block numbers. identifier return { block_number: number }
text string are detected as block tag. identifier return tag
null is detected as 'pending' block tag. identifier return 'pending'
Example
const result = new provider.Block(null).identifier;
// result = "pending"
