Struct DualStandardFilter 

pub struct DualStandardFilter { /* private fields */ }

A filter that matches against two standard 11-bit standard IDs.

The first filter part can match a packet’s id, RTR bit, and the first byte of the payload. The second filter part can match a packet’s id and RTR bit.

Warning: This is not a perfect filter. Extended IDs that match the bit layout of this filter will also be accepted.

Implementations

impl DualStandardFilter

pub const fn new( first_id: &BitFilter<11>, first_rtr: &BitFilter<1>, first_payload: &BitFilter<8>, second_id: &BitFilter<11>, second_rtr: &BitFilter<1>, ) -> Self

Create a filter that matches against two standard 11-bit standard IDs.

The first filter part can match a packet’s id, RTR bit, and the first byte of the payload. The second filter part can match a packet’s id and RTR bit.

Examples

A filter that matches any standard id that ends with a 00 or a 11, with any RTR, and with any payload on the first filter.

const FILTER: twai::filter::DualStandardFilter = twai::filter::DualStandardFilter::new(
    b"xxxxxxxxx00",
    b"x",
    b"xxxxxxxx",
    b"xxxxxxxxx11",
    b"x",
);

pub fn new_from_code_mask( first_id_code: StandardId, first_id_mask: StandardId, first_rtr_code: bool, first_rtr_mask: bool, first_payload_code: u8, first_payload_mask: u8, second_id_code: StandardId, second_id_mask: StandardId, second_rtr_code: bool, second_rtr_mask: bool, ) -> Self

The masks indicate which bits of the code the filter should match against. Set bits in the mask indicate that the corresponding bit in the code should match.
