Struct Error 

pub struct Error { /* private fields */ }

The error type for this library.

Implementations

impl Error

pub fn new<S: Into<String>>(error_type: ErrorType, site: S) -> Self

Create an Error with no message and no underlying cause. site is a file.rs:line string, as produced by the [site] macro.

pub fn with_message<S: Into<String>>(self, message: S) -> Self

Attach a human-readable message describing this particular failure.

pub fn with_source<E>(self, source: E) -> Self

where E: Error + Send + Sync + 'static,

Attach the underlying error that caused this one.

pub fn error_type(&self) -> ErrorType

A getter for the error_type field.

pub fn site(&self) -> &str

Where in this library the error was raised, e.g. src/lib.rs:31.

pub fn message(&self) -> Option<&str>

The message describing this particular failure, if one was attached.

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 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.
