Implementations

impl UnversionizeError

pub fn upgrade<E: Error + 'static + Send + Sync>( from_vers: &str, into_vers: &str, source: E, ) -> Self

pub fn conversion<E: Error + 'static + Send + Sync>( from_type: &str, source: E, ) -> Self

pub fn skipped_variant(variant_name: &str) -> Self

Trait Implementations

impl Debug for UnversionizeError

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

Formats the value using the given formatter.

impl Display for UnversionizeError

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

Formats the value using the given formatter.

impl Error for UnversionizeError

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<Infallible> for UnversionizeError

fn from(_value: Infallible) -> Self

Converts to this type from the input type.
