Struct LoxError 

pub struct LoxError(/* private fields */);

A type-erased error carrying an arbitrary failure across an abstraction boundary.

Unlike a transparent wrapper, LoxError exposes the erased error as its source, so the wrapped error remains reachable when walking an error chain with find_source.

Implementations

impl LoxError

pub fn new(error: impl Into<BoxedError>) -> Self

Wraps an arbitrary error.

pub fn into_inner(self) -> BoxedError

Returns the wrapped error.

pub fn downcast_ref<E: Error + 'static>(&self) -> Option<&E>

Searches the wrapped error and its source chain for an error of type E.

Trait Implementations

impl Debug for LoxError

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

Formats the value using the given formatter.

impl Display for LoxError

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

Formats the value using the given formatter.

impl Error for LoxError

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)
