Enum AddError

pub enum AddError {
    TypeMismatch {
        actual: &'static str,
        expected: &'static str,
    },
    DuplicateId(String),
}

An error returned when a value fails be added to a collection.

Variants

TypeMismatch

The value does not match the collection type.

Fields

actual: &'static str

The value type.

expected: &'static str

The collection type.

DuplicateId(String)

An ID is duplicated.

Trait Implementations

impl Clone for AddError

fn clone(&self) -> AddError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AddError

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

Formats the value using the given formatter.

impl Display for AddError

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

Formats the value using the given formatter.

impl Error for AddError

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 PartialEq for AddError

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