Solana: Order of elements in account_infos in invoke()

The role of the system of elements in account information on Solana

In the real development of the blockchain, in the Solana blockchain, the Invake () feature providing is pts and interacting with intelligent contractions. A crucial aspeect of this function is the management of information, it is essential to essentials the recipe and the recipient and transaction.

Вень it тки сыстем of elements in info, it may be a trim question, but its meaning cannot be overted. In this article, we will deepen Russian programs that interact with the Solana.

The context: Infos account on Solana

On the Solana blockchain, the accounts info are stored as tuuple wthin a strocture calling. There is tuuple contain varous relating to the dedeils of the sender, the recipients and transactions. When here thee infos accounts ininvoke ()functions, it is essentially theystand.

For example, consider the following example:

Rust

Use Solana_SDK :: Account_info :: Accounting;

Fn invokes (

Education: and instructions,

Account_infos: & [accounting],

) -> Result <(), Solana_sdk_error :: Error>

// processes information information in education

}

In this example, we are assuming that it is instructions containing a reference to script data and a matrix of account_infos. The array account_infos' class likes this:

Rust

[

    Accounting {

        Pub_key: "Pubkey1" .to_string (),

        Pub_Script: VEC! [], // vector void, indicaates no script data

        Account_id: 0,

        Public_key: "Publickey1" .to_string (),

        Program_id: 0,

        Scriptpubkeys: VEC! [],

        Program_index: 0,

    },

    Accounting {

        Pub_key: "Pubkey2" .to_string (),

        Pub_Script: VEC! [], // vector void, indicaates no script data

        Account_id: 1,

        Public_key: "Publickey2" .to_string (),

        Program_id: 0,

        Scriptpubkeys: VEC! [],

        Program_index: 0,

    },

"

Now, let’s examine theorder of the elements is in account_infos within. Suppose, the first Academy of it has a specific strocture:

`Rust

#[Derive (Debug)]

Stact accounting {

Pub_key: string,

Pub_script: vec ,

Account_id: U8,

Public_key: string,

Program_id: u8,

scriptpubkeys: vec ,

Program_index: u8,

}

“

The order of the elements inaccount_infos` is the scrug of because it determines the script information. If we are to what a Russian, that reads account information from an education, knowing that the correct system would allow us to:

• Identify this without information contains the script date

• Recover the relevant information (e.g. script length, program)

• Elaborate script data

In this example, if we reading and the sessions count.

Because the ordering of the elements is important

Although at the first glance it may be a see mine question, understanding the e. Gere are some reasons it:

* Recovery of the day the scripts

: Knowing the correct syndyccess the day. performance.

* Length the script and recovery of the program : By understanding. ript length and program) for procesing.

* Error management and debuts : the correct management of thements of help ylentify errors during debuts and improve the code.
