Variants

InvalidMessagePath

Message doesn’t have a valid format.

Message names must follow the package_name/MessageName format.

Packages must follow REP 144 rules.

Fields

name: String

Full name of the message we are trying to parse.

reason: String

Reason for the failure.

UnsupportedDataType

Field in the msg or srv file has a name that doesn’t fit any data type category.

Fields

name: String

Full name of the data type we are trying to parse.

reason: String

Reason for the failure.

BadMessageContent(String)

MessageDependencyMissing

Certain operations on a msg or srv file require first handling all messages it depends upon.

For example, to calculate an MD5 sum for a message, you first need to calculate it for all messages it depends upon, and passing them into the calculation call.

Fields

package: String

Package that the message is located in.

name: String

Name of the missing message.

BadConstant

Passed in constant value is not parsable as its data type.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
