Enum MarshalerError 

pub enum MarshalerError {
    InvalidCmdID {
        expected: u16,
        found: u16,
    },
    InvalidDataLength {
        expected: usize,
        found: usize,
    },
    BufferTooSmall {
        need: usize,
    },
    Unexpected {
        code: usize,
        message: &'static str,
    },
}

Errors returned by Marshaler::marshal, Marshaler::unmarshal, and RawFrame::unmarshal.

Variants

InvalidCmdID

The frame’s command ID does not match the expected type.

Returned by RawFrame::unmarshal when M::CMD_ID differs from the command ID in the decoded frame.

Fields

expected: u16

found: u16

InvalidDataLength

The payload length does not match Marshaler::PAYLOAD_SIZE.

Returned by RawFrame::unmarshal when the payload size in the frame differs from the size the target type expects.

Fields

expected: usize

found: usize

BufferTooSmall

The destination buffer is too small to hold the serialized payload.

need is the minimum buffer size required, in bytes.

Fields

need: usize

Unexpected

An error specific to the payload type prevented successful marshaling or unmarshaling.

This is a catch-all variant for errors that do not fit into the above categories. The inner error type and message are determined by the specific implementation of Marshaler::marshal or Marshaler::unmarshal.

Fields

code: usize

message: &'static str

Trait Implementations

impl Debug for MarshalerError

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

Formats the value using the given formatter.

impl Display for MarshalerError

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

Formats the value using the given formatter.

impl Error for MarshalerError

fn source(&self) -> Option<&(dyn Error + '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.
