Enum PackError 

pub enum PackError {
    BufferTooSmall {
        need: usize,
    },
    InvalidPayloadSize {
        expected: usize,
        found: usize,
    },
    MarshalerError(MarshalerError),
}

Errors returned by Messager::pack.

Variants

BufferTooSmall

The destination buffer is too small to hold the complete frame.

Fields

need: usize

The minimum required size in bytes: 5 (header) + 2 (CMD_ID) + PAYLOAD_SIZE + 2 (CRC16).

InvalidPayloadSize

The marshaler returned a byte count that does not equal Marshaler::PAYLOAD_SIZE.

This indicates a broken Marshaler implementation.

Fields

expected: usize

The expected payload size for the target type.

found: usize

The actual payload size returned by the marshaler.

MarshalerError(MarshalerError)

The marshaler returned an error.

Trait Implementations

impl Debug for PackError

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

Formats the value using the given formatter.

impl Display for PackError

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

Formats the value using the given formatter.

impl Error for PackError

fn source(&self) -> Option<&(dyn StdError + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Format for PackError

where MarshalerError: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl From<MarshalerError> for PackError

fn from(err: MarshalerError) -> Self

Converts to this type from the input type.
