Enum Error 

#[non_exhaustive]
pub enum Error {
    DictionaryLoad(String),
    Segmentation {
        hanja: String,
        reason: String,
    },
    InvalidReading {
        hanja: String,
        reading: String,
    },
    Internal(&'static str),
    Other(Box<dyn Error + Send + Sync + 'static>),
}

Error returned by fallible core pipeline entry points.

The core engine is mostly infallible today because dictionary lookup is a synchronous trait contract. This type is still the common structured error surface for reader/engine/writer boundaries and for future engine invariants that callers may need to inspect.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DictionaryLoad(String)

Loading or preparing a dictionary failed before conversion could run.

Segmentation

Lattice segmentation failed for a specific source string.

Fields

hanja: String

The hanja source span that could not be segmented.

reason: String

Human-readable reason for the segmentation failure.

InvalidReading

A dictionary or fallback path produced a reading that is not accepted.

Fields

hanja: String

The hanja source string associated with the reading.

reading: String

The rejected hangul reading.

Internal(&'static str)

An internal invariant was violated.

Other(Box<dyn Error + Send + Sync + 'static>)

A boxed error from an extension point that has no more specific core variant yet.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Box<dyn Error + Send + Sync>> for Error

fn from(source: Box<dyn Error + Send + Sync + 'static>) -> Self

Converts to this type from the input type.
