Title: Solana: Doubts about GettransactionCount, rather than doing so
entry
Solana is a popular Blockchain platform for fast and safe operations. When designing a program that interacts with the Solana network, it is necessary to understand how different functions work. In this article, we will examine two important salt functions: Gettransationcount and its use with Slotsubscriprib. We will also discuss some of the doubts we encountered in trying these functions.
Get the root slot number
You can use Slan SDK SLOTSUBSRIPT. Here is an example of how to use it:
`Rūdys
Use Solana-Program :: {{
Conct_info :: {Next_account_info, Conctinfo},
the entrance point,
Ententpoint :: Program,
Program_error :: Printerror,
Pubkey :: Pubkey,
};
The entrance point! (Program);
FN Main () -> “Programmeult” {
// Download the main socket number from account information
Let (slot_number, _) = Next_account_info (& Concountinfo :: New_indExed ());
Println! ("Root number: {}", slot_number);
OK (())
}
In this example, we subscribe to the “Slot” event in a specific socket (1". Once the event occurs with the number 1, we will get important information about the account. Let's dive deeper using the GettransactionCount.
Using GettransactionCount
Solan returns the total number of completed operations in the GettransactionCountcount. To use this feature, you must first get the block arrow and then call the Gettransationcount. Here is an example:
Rūdys
Use Solana_Rogram :: {{
Conct_info :: {Next_account_info, Conctinfo},
the entrance point,
Ententpoint :: Program,
Program_error :: Printerror,
Pubkey :: Pubkey,
};
The entrance point! (Program);
FN Main () -> “Programmeult” {
// Download the block arrow (in this case 1)
Allow Block_index = Next_account_info (& Concountinfo :: New_indExed ()). Pubkey;
// Call the GettransactionCount with a block arrow
Allow the operation_count = solana_program :: get_transACTION_COUNT (Block_index)?;
Println! ("Number of transitions: {}", "transaction_count");
OK (())
}
In this example, we receive information about the second cracks (“2”). Then we call “Gettransactioncount” with a block arrow. This feature returns the value of the U128 reflecting the total number of completed operations.
DRESIDENTS
After testing these features in our examples of programs, we encountered some doubts:
- In contrast, Slotsubscript is designed to operate with a Loot event that begins with a new socket or updated.
- BLOCK Arrow : Block arrow returned by The Next_account_info does not always match the socket number. Instead of getting the right result, we need to use “block_index.”

program
In this article, we have explored two important Solanie features: Gettransationcount and its use with SLOTSUBSRRIPRE. We discussed some doubts we encountered in trying these functions and gave examples to show how to use them correctly. By understanding the basics of Solan programming and these features, you are on the right path to create powerful programs interacting with the Solana network.
