Builder errors

Most of the Thing Description conflicts are caught at compile time. The few errors that may be discovered at only runtime are the following.

Variants

DuplicatedSecurityDefinition(String)

The WoT security definitions must have an unique name

MissingOpInForm

The forms have defaults that depend on the Affordance that contains them. The Thing-level forms must be explicit on the operation

InvalidOpInForm

The Form can use only a specific set of operations depending on the context.

Fields

context: FormContext

The context of the invalid operation.

operation: FormOperation

The invalid operation for the Form.

UndefinedSecurity(String)

The security field must refer to existing security definitions.

InvalidMinMax

When both min and max are specified, min must be less or equal than max

NanMinMax

Neither minimum or maximum value can be NaN

DuplicatedAffordance

For each type of affordance, names must be unique

Fields

ty: AffordanceType

The type of the affordance

name: String

The duplicated name

InvalidMultipleOf

Invalid multiple_of field, that must strictly greater than zero.

MissingSchemaDefinition(String)

A schema has been referenced using a specific name, but it is not been declared.

InvalidUriVariables

Invalid URI variable, which cannot be an object or an array.

InvalidLanguageTag(String)

Language tag is not conforming to BCP47.

SizesWithRelNotIcon

A Link contains a sizes field but its rel field is not equal to icon.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Error

impl StructuralPartialEq for Error
