}

Enumeration of all possible error kinds in the Oak Core framework.

This enum categorizes different types of language that can occur during parsing operations, each with specific associated data relevant to that error type.

Variants

IoError

I/O error that occurred while reading source files.

Fields

error: Error

The underlying I/O error.

url: Option<Url>

Optional URL of the file that caused the error.

SyntaxError

Syntax error encountered during parsing.

Fields

message: String

Human-readable error message describing the kind issue.

source: SourceLocation

Location in the source code where the error occurred.

UnexpectedCharacter

Unexpected character encountered during lexical analysis.

Fields

character: char

The character that was not expected at this position.

source: SourceLocation

Location in the source code where the unexpected character was found.

CustomError

Custom error for user-defined error conditions.

Fields

message: String

The error message describing the custom error condition.

Trait Implementations

impl Clone for OakErrorKind

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OakErrorKind

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

Formats the value using the given formatter.

impl Display for OakErrorKind

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

Formats the value using the given formatter.

impl Error for OakErrorKind

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<OakErrorKind> for OakError

fn from(kind: OakErrorKind) -> Self

Converts to this type from the input type.
