Enum FaultConfinementState

Source 
pub enum FaultConfinementState {
    ErrorActive,
    ErrorPassive,
    BusOff,
}
Expand description

The 3 fault confinement states as described in the CAN 2.0 spec.

Variants§

§

ErrorActive

Errors are so few that this interface tells the whole bus when they happen.

§

ErrorPassive

Errors are numerous enough that informing the bus of them isn’t allowed, but regular Rx and Tx can still work.

§

BusOff

There are so many bus errors that we’re effectively not connected, Rx and Tx are disabled.
