Struct canadensis_can::TransferCrc

pub struct TransferCrc { /* private fields */ }

Calculates the 32-bit transfer CRC

Implementations

impl TransferCrc

pub fn new() -> Self

Creates a new CRC calculation

Examples found in repository

examples/crc.rs (line 16)

fn main() -> Result<(), Box<dyn Error>> {
    let mut crc = TransferCrc::new();
    for byte in env::args().skip(1).map(|arg| u8::from_str_radix(&arg, 16)) {
        let byte = byte?;
        crc.add(byte);
    }
    println!("{:#06x}", crc.get());

    Ok(())
}

pub fn add(&mut self, byte: u8)

Adds a byte to the CRC calculation

Examples found in repository

examples/crc.rs (line 19)

fn main() -> Result<(), Box<dyn Error>> {
    let mut crc = TransferCrc::new();
    for byte in env::args().skip(1).map(|arg| u8::from_str_radix(&arg, 16)) {
        let byte = byte?;
        crc.add(byte);
    }
    println!("{:#06x}", crc.get());

    Ok(())
}

pub fn add_bytes(&mut self, bytes: &[u8])

Adds all the bytes in a slice to the CRC calculation

pub fn get(&self) -> u16

Returns the CRC calculated over the bytes added through previous calls

Examples found in repository

examples/crc.rs (line 21)

fn main() -> Result<(), Box<dyn Error>> {
    let mut crc = TransferCrc::new();
    for byte in env::args().skip(1).map(|arg| u8::from_str_radix(&arg, 16)) {
        let byte = byte?;
        crc.add(byte);
    }
    println!("{:#06x}", crc.get());

    Ok(())
}
