Solana: deserialize program data in log notification
I can provide you with an article on how to derive program data in a log notification using Borsh serialization.
Borsh serialization and deserving in Solana programs **
Solana programs are written in rust, but also use the Borsh library (binary objects root roots of objects) to serialize. This library provides efficient methods for serializing and deserving data structures, including those used in Solana programs.
In this article, we will explore how to derise program data in a log notification using Borsh serialization in blockchain Solana.
What is logo notification
A log’s notification in Solana is an event that occurs during the execution of a transaction. It contains relevant information about the transaction, such as the account that triggered the event and the amount transferred.
Borsh Basic Serialization
Before we dive into the data from the desiremizing program of a log notification, we will quickly revise the Borsh serialization Basics. Borsh is a quick and compact binary serialization format for rust. Here are some aspects -Borsh Chave:
* STRESTS : Borsh supports structure definitions using the word -chau struct.
* FIELDS : Borsh fields can be defined with optional type parameters.
* NULLABILITY : Borsh can represent null values (represented by an empty field) or non -null values.
* Coding : Borsh encodes binary data in a compact format.
DESERIZING DATE OF THE LOG NOTIFICATION PROGRAM
To derise program data from a log notification using Borsh, we need:
- Define the structure that contains the unprecedented data
- Create an instance of the structure
- Pass the encoded log notification data
Here is some sample code for these steps:
`Rust
Use Borsh :: {Borshdeserialize, Borshencode};
// Define the structure that maintains program data from a log notification
#[Deriva (Borshdeserialize)]]
Programmdata strict {
Name: String,
}
Fn Main () {
// Create an instance of the program program
Leave Mut Program_Data = Programming :: Default ();
// encodes logo notification in binary format
Be coded_log_notification =
// Suppose you have a logging structure with this method to codify
CODED_LOG_NOTIFICATION (). Into_bytes ();
// DESERADE LOG NOTIFICATION IN THE DATA STRUCT PROGRAM
Borshdecode :: New ::
.unwrap()
.Ldeme (“Stolen of Error”);
}
`
Running the code
To execute this code, you will need to add a Borsh elog-notify facilities to yourposition.Toml file:
`Toml
[Dependencies]
Borsh = “0.4.3”
Log-Notify = “0.1.1”
`
Then compile the program with the following command:
`Bash
Load construction
`
Run the compiled binary using:
`Bash
.
`
This should generate the desatiated ‘programmdata’ structure.
Conclusion
In this article, we explore how to desire program data from a log notification in Solana programs using Borsh serialization. Following these steps and understanding the Borsh Basics, you can efficiently serialize and deserve the data structures used in your Solana programs.
