Struct SyncCounter 

pub struct SyncCounter { /* private fields */ }

The counter for a SYNC producer (CiA 301 §7.2.5.2.1).

When enabled, the counter cycles 1..=overflow and wraps back to 1. Constructed from the object 0x1019 overflow value: 0 (or the reserved 1) means the producer emits empty SYNC frames, so SyncCounter::advance yields None.

Implementations

impl SyncCounter

pub fn new(overflow: u8) -> Result<Self>

Create a SYNC counter from an overflow value.

Returns Error::InvalidSyncCounter unless overflow is 0 or in 2..=240.

pub const fn is_counting(&self) -> bool

Whether this producer emits a counter (overflow in 2..=240).

pub fn advance(&mut self) -> Option<u8>

Advance to the next SYNC counter value.

Returns None for a counter-less producer (emit an empty SYNC), or Some(count) cycling 1..=overflow.
