Struct embassy_stm32::can::filter::Mask32

pub struct Mask32 { /* private fields */ }

A 32-bit identifier mask.

Implementations

impl Mask32

pub fn accept_all() -> Self

Creates a 32-bit identifier mask that accepts all frames.

This will accept both standard and extended data and remote frames with any ID.

pub fn frames_with_ext_id(id: ExtendedId, mask: ExtendedId) -> Self

Creates a 32-bit identifier mask that accepts all frames with the given extended ID and mask combination.

Filter logic: frame_accepted = (incoming_id & mask) == (id & mask)

A mask of all all ones (0x1FFF_FFFF) matches an exact ID, a mask of 0 matches all IDs.

Both data and remote frames with id will be accepted. Standard frames will be rejected.

pub fn frames_with_std_id(id: StandardId, mask: StandardId) -> Self

Creates a 32-bit identifier mask that accepts all frames with the given standard ID and mask combination.

Filter logic: frame_accepted = (incoming_id & mask) == (id & mask)

A mask of all all ones (0x7FF) matches the exact ID, a mask of 0 matches all IDs.

Both data and remote frames with id will be accepted. Extended frames will be rejected.

pub fn data_frames_only(&mut self) -> &mut Self

Make the filter accept data frames only.

pub fn remote_frames_only(&mut self) -> &mut Self

Make the filter accept remote frames only.
