Struct ErrorCounts 

#[non_exhaustive]
pub struct ErrorCounts {
    pub bit: u32,
    pub form: u32,
    pub stuff: u32,
    pub acknowledge: u32,
    pub other: u32,
    pub arbitration_lost: u32,
    pub overrun: u32,
    pub queue_full: u32,
}

Available on crate feature unstable only.

What the controller has reported since the driver was last started (TwaiConfiguration::start), as counted by the async driver’s interrupt handler (a blocking driver counts nothing).

Bus errors are classified from the error code capture register as ESP-IDF does: bit, form and stuff errors by type, an acknowledgement error by the ACK slot segment, anything else as other.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

bit: u32

Bit errors

form: u32

Form errors

stuff: u32

Stuff errors

acknowledge: u32

Acknowledgement errors: nobody acknowledged a transmitted frame

other: u32

Other bus errors

arbitration_lost: u32

Arbitration lost while transmitting (the controller retries)

overrun: u32

Frames lost in the controller: its receive FIFO overran

queue_full: u32

Frames lost because the driver’s receive queue was full
