Struct Error

pub struct Error { /* private fields */ }

This crate’s error structure which internal errors are converted into.

The error is split into a general message and a context string. For parsing, for instance, the context string is populated with a snippet of the source text, while for validation the context is populated with a list of errors.

The Error implements both the fmt::Display and fmt::Debug traits. It also implements

Implementations

impl Error

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

Create a new Error with only a main message from an input string.

pub fn new_with_context<S: Into<String>>( message: S, location: Option<Location>, context: S, error_type: Option<ErrorType>, ) -> Self

Create a new Error with a main message and a context string from two input strings.

pub fn message(&self) -> &str

Returns the message of the current error. The context is discarded.

pub fn location(&self) -> &Option<Location>

Returns the location of the current error.

pub fn print(&self, include_ctx: bool) -> String

Formats this error, with the option to include the context information as well, which will cause the string to be multi-line.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
