Struct UnknownVariant 

pub struct UnknownVariant {
    pub value: String,
}

Error returned by an enum’s from_wire strict parser when the input string does not correspond to any variant defined in this schema version.

Unlike the serde / FromStr deserialization path — which maps every unrecognized value to the forward-compatibility Unknown catch-all — the generated T::from_wire associated function returns this error for values that are not part of the current BO4E schema. Use it at the ingest boundary to reject typos, legacy codes, or values from a newer schema, instead of having them silently degrade to Unknown.

Example

use rubo4e::current::Marktrolle;

assert!(Marktrolle::from_wire("LF").is_ok());
// Legacy / typo'd values are rejected rather than silently accepted:
assert!(Marktrolle::from_wire("LFG").is_err());

Fields

value: String

The unrecognized wire value that was rejected.

Implementations

impl UnknownVariant

pub fn new(value: impl Into<String>) -> Self

Constructs an UnknownVariant from the offending wire value.

Trait Implementations

impl Clone for UnknownVariant

fn clone(&self) -> UnknownVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnknownVariant

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

Formats the value using the given formatter.

impl Display for UnknownVariant

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

Formats the value using the given formatter.

impl Eq for UnknownVariant

impl Error for UnknownVariant

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<UnknownVariant> for Error

Available on crate feature validate only.

fn from(e: UnknownVariant) -> Self

Converts an UnknownVariant into a garde::Error so strict enum parsing can participate in garde-driven validation pipelines.

impl PartialEq for UnknownVariant

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

Equality operator ==.

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

Inequality operator !=.
