Struct OneWireCrc 

pub struct OneWireCrc(/* private fields */);

Calculate CRC-8 used in 1-Wire communications.

Implementations

impl OneWireCrc

pub fn value(&self) -> u8

Get the current CRC value

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

Update the CRC with the incoming byte.

Arguments

• byte - The byte to update the CRC with.

Note

This method uses a lookup table for CRC calculation if the crc-table feature is enabled. Otherwise, it uses bit shifts and XOR operations for CRC calculation.

pub fn validate(sequence: &[u8]) -> bool

Valudate a sequence of bytes where the last byte is the 1-Wire CRC of the previous bytes.

Note

For such a sequence, the CRC should be 0x00.

Trait Implementations

impl Debug for OneWireCrc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for OneWireCrc

fn default() -> OneWireCrc

Returns the “default value” for a type.
