Enum AttributeError 

pub enum AttributeError {
    DuplicateKey {
        key: String,
        tiers: Vec<Tier>,
    },
    EmptyFacetSet {
        port: String,
    },
    DuplicatePortName {
        name: String,
    },
}

Errors raised by attribute-layer construction and validation.

Variants

DuplicateKey

The same key appears in multiple tiers on one entity.

Fields

key: String

The conflicting key.

tiers: Vec<Tier>

Every tier the key was seen in.

EmptyFacetSet

A plug or socket declared no facets.

Fields

port: String

The offending port name.

DuplicatePortName

Two plugs, two sockets, or a plug and a socket share a name.

Fields

name: String

The duplicated port name.

Trait Implementations

impl Debug for AttributeError

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

Formats the value using the given formatter.

impl Display for AttributeError

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

Formats the value using the given formatter.

impl Error for AttributeError

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 From<AttributeError> for ElementError

fn from(source: AttributeError) -> Self

Converts to this type from the input type.

impl From<AttributeError> for Error

fn from(source: AttributeError) -> Self

Converts to this type from the input type.

impl From<AttributeError> for ParameterError

fn from(source: AttributeError) -> Self

Converts to this type from the input type.

impl PartialEq for AttributeError

fn eq(&self, other: &AttributeError) -> 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.
