Implementations

impl ComponentError

pub fn code(&self) -> &'static str

A stable, language-agnostic identifier for this error’s kind, independent of its human-readable message and never changing across releases for the same variant. Generated bindings prefix the message with this (see alef::backends::native_components) so callers in any host language can distinguish, for example, an offline failure from an invalid signature from an unsupported host without parsing free-form text.

Trait Implementations

impl Debug for ComponentError

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

Formats the value using the given formatter.

impl Display for ComponentError

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

Formats the value using the given formatter.

impl Error for ComponentError

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<Error> for ComponentError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ComponentError

fn from(source: Error) -> Self
