open static fun fromHexStringStrict(str: CharSequence!): Bytes32! (source)
Parse a hexadecimal string into a Bytes32.
This method is extra strict in that str must of an even length and the provided representation must have exactly 32 bytes.
str - CharSequence!: The hexadecimal string to parse, which may or may not start with "0x".
