Trait HasChecksumField 

Source 
pub trait HasChecksumField {
    // Required methods
    fn calculate_checksum(&self) -> Result<u16, OtToolsIoError>;
    fn check_checksum(&self) -> Result<bool, OtToolsIoError>;
}
Expand description

A type has a checksum field which needs implementations to handle calculation and validation

Required Methods§

Source

fn calculate_checksum(&self) -> Result<u16, OtToolsIoError>

Method for calculating the checksum value for types that have a checksum field

use ot_tools_io::{HasChecksumField, OctatrackFileIO, BankFile};
let bank = BankFile::from_data_file(&path).unwrap();
assert_eq!(bank.checksum, bank.calculate_checksum().unwrap())
Source

fn check_checksum(&self) -> Result<bool, OtToolsIoError>

Method to verify if checksum is valid in some data type. See this thread.

use ot_tools_io::{HasChecksumField, OctatrackFileIO, BankFile};
// true for valid checksum values
assert!(BankFile::from_data_file(&path).unwrap().check_checksum().unwrap())
