Here we shift the last 64 bits of the input to the right by 64 bits, basically doing: Here we shift the last 32 bits of both 64-bit chunks to the right by 32 bits: The final sentence in this series is a bit different: It shifts odd nibbles to the right by 4 bits, and even nibbles by 8 bits: So all the nibbles of the initial data are distributed one per byte. :). Kyber and Dilithium explained to primary school students? The ethers.js coder was used because it is robust and well tested and was the only implementation of ABIv2.

Microsoft Azure joins Collectives on Stack Overflow. To mimic the web3 coercion of short string into bytes32 you can use the following; but please be aware you are relying on incorrect behaviour, so terrible things will happen, if for example the string is over 32 bytes (not necessarily characters) long: To give a quick example of how the web3 behaviour can cause your entire application to behave in wildly unpredictable ways (possibly exposing it to attacks); imagine if you accept user input from a web form which is a string: @ricmoo thanks! In C it is usually defined as. It seems that this issue doesn't arise when using ethers.js though so I've gone ahead and updated my smart contract to use strings!

If you're storing the length of the string too, then I guess you've saved one byte at the cost of whatever the size of your variable is (likely 4 bytes), and gained faster access to the length of said string. Now with every byte x we need to do the following transformation: Note, that (x < 10 ? I can make the function emulate that behaviour. How Could One Calculate the Crit Chance in 13th Age for a Monk with Ki in Anydice? Is it realistic for an actor to act in four movies in six months?

Let us see what happens if you load a document with a final nul in JavaScript: So if you pad the end of your JSON strings with nulls, they won't parse in JavaScript and Python. It would be much cleaner to have a separate field for len. Depending on the number of strings stored, this can be high overhead. You could replace that \0 with anything, like t. This is not a bug, but should be an error in any well-formed parser. They have a python implementation that passes a value to this mapping from a function that looks like this. Meaning end of the value present in the bytes32 variable. Often it doesnt matter, but just something to keep in mind, because it could.
