Enum NameScopeValueError 

pub enum NameScopeValueError {
    Completed,
    DuplicateName(String),
    UnsupportedValue,
    NullValue,
}

Why a value could not be registered in a name scope (INameScope::try_register_value): the errors of NameScopeError and the ones only a value can have.

Variants

Completed

The name scope is completed: no further registrations are allowed.

DuplicateName(String)

Another value is registered with the name.

UnsupportedValue

A custom scope that only implements the registration of objects of the object model was given another value.

NullValue

The value is null (a boxed nullable that holds no value).

Trait Implementations

impl Clone for NameScopeValueError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NameScopeValueError

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

Formats the value using the given formatter.

impl Display for NameScopeValueError

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

Formats the value using the given formatter.

impl Eq for NameScopeValueError

impl Error for NameScopeValueError

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<NameScopeError> for NameScopeValueError

fn from(error: NameScopeError) -> Self

Converts to this type from the input type.

impl PartialEq for NameScopeValueError

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

Equality operator ==.

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

Inequality operator !=.
