Struct BoxError 

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

A backend error erased to one concrete type, so backends with differing associated Errors can be stored behind a single trait object.

Transparent wrapper: Display delegates to the inner error and source exposes it, so logs and error chains read exactly as the un-erased error did.

Implementations

impl BoxError

pub fn new<E: EmbeddingError>(err: E) -> Self

Erase any EmbeddingError into a BoxError.

Trait Implementations

impl Debug for BoxError

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

Formats the value using the given formatter.

impl Display for BoxError

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

Formats the value using the given formatter.

impl Error for BoxError

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.
