Here’s an example of how you can use the calculate_at_percentage function with multiple parameters and call it from within your Rust contract:
use solana_program::{
account_info::{ next_account_info, AccountInfo },
entrypoint::ProgramResult,
program_error::PrintError,
program_error::PrintErrorExt,
pubkey::Pubkey,
};
// Define the calculate_at_percentage function
fn calculate_at_percentage(percent: f64, params...) -> ProgramResult {
// Call the base function with additional parameters
let result = solana_program::instruction::new(
&[
// Add your on-chain iteration compute units usage here (e.g., "1000", "20000")
("IterationComputeUnitsUsage", 1000),
// Add other parameters as needed
("AdditionalParam1", 10.5),
// Add more parameters as needed
],
&[
Pubkey::new_unique(&solana_program::program_id()),
next_account_info(),
]
);
solana_program::assert_valid_instruction(&result)?;
Ok(())
}
// Call the function with multiple parameters
fn main() -> ProgramResult {
// Define some example parameters
let params = (1000, 20.5, "IterationComputeUnitsUsage", 10);
calculate_at_percentage(percent: params.0, params.1, params.2)?;
Ok(())
}
In this example, the calculate_at_percentage function takes an optional number of parameters with default values ​​(e.g., "1000", "20.5", etc.). You can call it from within your contract using the next_account_info function to get a new account object.
Note that you will need to modify your contract to handle the additional parameters and ensure that they are called correctly. Additionally, you may need to add error handling to deal with cases where the input parameters are not valid or if there are errors during execution.
Also, keep in mind that Solana has some specific requirements for how functions can be defined and used within a contract. You should consult the [Solana Programming Language documentation]( for more information on best practices and guidelines.
