Shared trait for CAN frames

Required Methods§

Source

fn id_word(&self) -> canid_t

Get the composite SocketCAN ID word, with EFF/RTR/ERR flags

Source

fn set_id(&mut self, id: impl Into<Id>)

Sets the CAN ID for the frame

Source

fn set_data(&mut self, data: &[u8]) -> Result<(), ConstructionError>

Sets the data payload of the frame.

Provided Methods§

Source

fn from_raw_id(id: u32, data: &[u8]) -> Option<Self>

Creates a frame using a raw, integer CAN ID.

If the id is <= 0x7FF, it’s assumed to be a standard ID, otherwise it is created as an Extended ID. If you require an Extended ID <= 0x7FF, use new().

Source

fn remote_from_raw_id(id: u32, dlc: usize) -> Option<Self>

Creates a remote frame using a raw, integer CAN ID.

If the id is <= 0x7FF, it’s assumed to be a standard ID, otherwise it is created as an Extended ID. If you require an Extended ID <= 0x7FF, use new_remote().
