Struct Error 

pub struct Error { /* private fields */ }

An error signaled by general-purpose extension logic.

This is used for helper logic that is not related to a specific implementation of Read or Write. It may either represent a logical error (e.g. unexpected end of stream) or be a wrapper for an inner error that came from underlying implementation-specific logic.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Enrichable for Error

fn add_enrichment(&mut self, entry: EnrichmentEntry)

Adds enrichment information to the error.

impl Error for Error

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 ErrorExt for Error

fn message(&self) -> String

Returns the formatted error message without backtrace.

fn backtrace(&self) -> &Backtrace

Returns a reference to the captured backtrace.

fn has_backtrace(&self) -> bool

Returns true if the error has a captured backtrace.

fn find_source<T>(&self) -> Option<&T>

where T: Error + 'static,

Finds the first source error of the specified type in the error chain.

fn find_source_with<T>(&self, search: impl Fn(&T) -> bool) -> Option<&T>

where T: Error + 'static,

Finds the first source error of the specified type that matches the given predicate.

impl From<Infallible> for Error

fn from(_: Infallible) -> Self

Converts to this type from the input type.
