Struct PdoMapping 

pub struct PdoMapping<const N: usize> { /* private fields */ }

An ordered PDO mapping of up to N entries.

The mapped objects are packed into the frame in insertion order, and the total width may not exceed eight bytes (64 bits).

Implementations

impl<const N: usize> PdoMapping<N>

pub const fn new() -> Self

An empty mapping.

pub fn push(&mut self, entry: MappingEntry) -> Result<()>

Append a mapping entry.

Returns Error::PdoTooLong if it would push the total past 64 bits, or Error::MappingFull if the fixed capacity N is exhausted.

pub fn entries(&self) -> &[MappingEntry]

The mapping entries, in packing order.

pub fn len(&self) -> usize

The number of mapped entries (the value of mapping subindex 0).

pub fn is_empty(&self) -> bool

Whether the mapping is empty (PDO disabled).

pub fn total_bits(&self) -> u32

The total width of the mapped data, in bits.

pub fn total_bytes(&self) -> usize

The total width of the mapped data, in whole bytes (the CAN frame DLC).

Trait Implementations

impl<const N: usize> Debug for PdoMapping<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const N: usize> Default for PdoMapping<N>

fn default() -> Self

Returns the “default value” for a type.
