Enum DispatcherError 

pub enum DispatcherError {
    MissingCoverage {
        missing: Vec<String>,
    },
    DuplicateHelper {
        kind: String,
    },
    UnknownKind {
        kind: String,
    },
}

Build-time / seal-time dispatcher error.

Variants

MissingCoverage

One or more variant kinds reflected by V::variant_kinds() have no registered helper. Surfaces the exact missing kinds so the consumer can fix at compile time.

Fields

missing: Vec<String>

DuplicateHelper

Two helpers registered for the same kind. The dispatcher refuses ambiguity — pick one.

Fields

kind: String

UnknownKind

An applied variant carried a kind not in the variant universe. Can only happen if the variant enum was hand- constructed via serde without the typed enum (i.e. the reflection contract was violated upstream).

Fields

kind: String

Trait Implementations

impl Debug for DispatcherError

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

Formats the value using the given formatter.

impl Display for DispatcherError

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

Formats the value using the given formatter.

impl Error for DispatcherError

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.
