Struct Error 

pub struct Error<'a> { /* private fields */ }

Implementations

impl<'a> Error<'a>

pub fn new<T: Display>(message: T, info: Option<Span<'a>>) -> Self

Trait Implementations

impl<'a> Clone for Error<'a>

fn clone(&self) -> Error<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Error<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Error<'a>

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<'a> From<Error> for Error<'a>

fn from(e: FormatterError) -> Error<'a>

Converts to this type from the input type.

impl<'a> PartialEq for Error<'a>

fn eq(&self, other: &Error<'a>) -> 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.

impl<'a> Traceback for Error<'a>

fn message(&self) -> String

fn with(&self, caller: Caller) -> Self

fn callers(&self) -> Vec<Caller>

fn callers_to_string(&self, indent: usize) -> String

fn highlight_message(&self) -> String

fn previous_as_debug(&self) -> String

fn previous_as_string(&self) -> String
