Struct canadensis_filter_config::Filter

pub struct Filter { /* private fields */ }

A generic mask-based filter for extended CAN IDs

A filter will accept a message if (message_id & filter.mask) == (filter.id & filter.mask).

Implementations

impl Filter

pub fn new(mask: u32, id: u32) -> Self

Creates a filter

If the mask or ID is too large to fit into 29 bits, it will be silently truncated.

pub fn exact_match(id: u32) -> Self

Creates a filter that matches exactly one message ID

If the ID is too larg to fit into 29 bits, it will be silently truncated.

pub fn mask(&self) -> u32

Returns the mask of this filter, which indicates the bits that are checked

pub fn id(&self) -> u32

Returns the message ID that this filter (partially) matches

pub fn accepts(&self, id: u32) -> bool

Returns true if this filter accepts a message with the provided ID
