Struct SourceError

pub struct SourceError<E> { /* private fields */ }

A wrapper around error types which includes a SourceLocation.

This error is used to describe erros in the TableGen source file at a certain location.

By calling add_source_info, information about the TableGen source file at the SourceLocation will be included in this error.

Implementations

impl<E: Error> SourceError<E>

pub fn new(location: SourceLocation, error: E) -> Self

Creates a new SourceError.

pub fn location(&self) -> &SourceLocation

pub fn error(&self) -> &E

pub fn set_error<F: Error>(self, error: F) -> SourceError<F>

Replaces the inner error with the given error.

Any source information that was previously attached with SourceError::add_source_info will be removed.

pub fn set_location(self, location: impl SourceLoc) -> Self

Replaces the location.

Any source information that was previously attached with SourceError::add_source_info will be removed.

pub fn add_source_info(self, info: SourceInfo<'_>) -> Self

Adds information about the TableGen source file at the given SourceLocation to this error.

A new error message will be created by SourceMgr class of LLVM.

Trait Implementations

impl<E: Clone> Clone for SourceError<E>

fn clone(&self) -> SourceError<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for SourceError<E>

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

Formats the value using the given formatter.

impl<E: Error> Display for SourceError<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for SourceError<E>

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<TableGenError> for SourceError<TableGenError>

fn from(value: TableGenError) -> Self

Converts to this type from the input type.

impl<E: PartialEq> PartialEq for SourceError<E>

fn eq(&self, other: &SourceError<E>) -> 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.
