Struct arithmetic_typing::error::Error

pub struct Error<Prim: PrimitiveType> { /* private fields */ }

Type error together with the corresponding code span.

Implementations

impl<Prim: PrimitiveType> Error<Prim>

pub fn kind(&self) -> &ErrorKind<Prim>

Gets the kind of this error.

pub fn main_location(&self) -> Location

Gets the most specific code span of this error.

pub fn root_location(&self) -> Location

Gets the root code location of the failed operation. May coincide with Self::main_location().

pub fn context(&self) -> &ErrorContext<Prim>

Gets the context for an operation that has failed.

pub fn path(&self) -> &[ErrorPathFragment]

Gets the path of this error relative to the failed top-level operation. This can be used for highlighting relevant parts of types in Self::context().

Trait Implementations

impl<Prim: Clone + PrimitiveType> Clone for Error<Prim>

fn clone(&self) -> Error<Prim>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Prim: Debug + PrimitiveType> Debug for Error<Prim>

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

Formats the value using the given formatter.

impl<Prim: PrimitiveType> Display for Error<Prim>

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

Formats the value using the given formatter.

impl<Prim: PrimitiveType> Error for Error<Prim>

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
