Struct CoreError 

pub struct CoreError { /* private fields */ }

An FFI-independent error shared by all Lindera language bindings.

Carries an ErrorKind category plus a human-readable message. Each binding implements a single From<CoreError> to map it onto its native exception type.

Implementations

impl CoreError

pub fn new(kind: ErrorKind, message: impl Into<String>) -> Self

Creates a new error with the given kind and message.

pub fn invalid_argument(message: impl Into<String>) -> Self

Creates an ErrorKind::InvalidArgument error.

pub fn dictionary(message: impl Into<String>) -> Self

Creates an ErrorKind::Dictionary error.

pub fn build(message: impl Into<String>) -> Self

Creates an ErrorKind::Build error.

pub fn validation(message: impl Into<String>) -> Self

Creates an ErrorKind::Validation error.

pub fn runtime(message: impl Into<String>) -> Self

Creates an ErrorKind::Runtime error.

pub fn kind(&self) -> ErrorKind

Returns the error category.

pub fn message(&self) -> &str

Returns the human-readable error message.

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> CoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Writes the error message (the kind is available via CoreError::kind).

impl Eq for CoreError

impl Error for CoreError

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<LinderaError> for CoreError

fn from(err: LinderaError) -> Self

Maps a lindera::error::LinderaError onto a CoreError, translating the LinderaErrorKind into the binding-facing ErrorKind.

impl PartialEq for CoreError

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