Struct conerror::Error

pub struct Error(/* private fields */);

Error with location information

Implementations

impl Error

pub fn new<T>( error: T, file: &'static str, line: u32, func: &'static str, module: &'static str ) -> Self

where T: Into<Box<dyn Error + Send + Sync>>,

Create an Error with location information.

pub fn plain<T>(error: T) -> Self

where T: Into<Box<dyn Error + Send + Sync>>,

Create an Error without location information

pub fn chain<T>( error: T, file: &'static str, line: u32, func: &'static str, module: &'static str ) -> Self

where T: Error + Send + Sync + 'static,

Same as Error::new if error is not of type Error, otherwise add location information to error if not created by Error::plain

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

Return the location information

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)>

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.
