Enum ReprInstantiateError 

pub enum ReprInstantiateError {
    AlreadyExists(DeclarationPtr, &'static str),
    ConflictingRepresentation {
        declaration: DeclarationPtr,
        existing: &'static str,
        requested: &'static str,

    Other(Error),
}

Errors that can be thrown by ReprDomainLevel::instantiate

Variants

AlreadyExists(DeclarationPtr, &'static str)

An instance of this representation already exists for this variable

ConflictingRepresentation

Channelling is disabled and another representation has already been selected.

Fields

declaration: DeclarationPtr

existing: &'static str

requested: &'static str

NoDomain(DeclarationPtr)

The given variable had no domain

BadKind(DeclarationPtr, String)

The given variable was of an unsupported kind

BadDomain(DeclarationPtr, Moo<Domain>)

This variable’s domain is different from the one this domain-level representation is for

Other(Error)

Can’t instantiate representation for a different reason

Trait Implementations

impl Debug for ReprInstantiateError

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

Formats the value using the given formatter.

impl Display for ReprInstantiateError

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

Formats the value using the given formatter.

impl Error for ReprInstantiateError

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<Error> for ReprInstantiateError

fn from(source: Error) -> ReprInstantiateError

Converts to this type from the input type.

impl From<ReprInstantiateError> for ReprError

fn from(source: ReprInstantiateError) -> ReprError

Converts to this type from the input type.

impl From<ReprInstantiateError> for ReferenceReprError

fn from(source: ReprInstantiateError) -> ReferenceReprError

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
