Struct Error 

pub struct Error {
    pub kind: ErrorKind,
    pub err: Box<dyn AnyError>,
    pub loc: Location,
    pub backtrace: Backtrace,
}

Shared error envelope and result type used by fallible IR APIs. An error object that can hold any core::error::Error.

Fields

kind: ErrorKind

The kind of error this is

err: Box<dyn AnyError>

The actual error object describing the error

loc: Location

Location of this error in the code being compiled

backtrace: Backtrace

Details of how this error occurred

Implementations

impl Error

pub fn loc(&self) -> &Location

Get a reference to this error’s Location.

pub fn set_loc(&mut self, loc: Location)

Set this error’s Location.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

This does not print Location or Backtrace. Use Printable::disp for that.

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

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.
