alloy's from_str calls from_hex

Making use of hex::decode_to_array

Creates an instance of type Self from the given hex string, or fails with a custom error type.

Both, upper and lower case characters are valid and can even be mixed (e.g. f9b4ca, F9B4CA and f9B4Ca are all valid strings).

H256 from_str:

/// Creates a hash type instance from the given string.
///
/// # Note
///
/// The given input string is interpreted in big endian.
///
/// # Errors
///
/// - When encountering invalid non hex-digits
/// - Upon empty string input or invalid input length in general
fn from_str(input: &str) -> $crate::core_::result::Result<$name, $crate::rustc_hex::FromHexError> {
	let input = input.strip_prefix("0x").unwrap_or(input);
	let mut iter = $crate::rustc_hex::FromHexIter::new(input);
	let mut result = Self::zero();
	for byte in result.as_mut() {
		*byte = iter.next().ok_or(Self::Err::InvalidHexLength)??;
	}
	if iter.next().is_some() {
		return Err(Self::Err::InvalidHexLength)
	}
	Ok(result)
}

Both methods strip the prefix and seem to work the same.
