Struct Error

pub struct Error { /* private fields */ }

Error type

Implementations

impl Error

pub fn new<S: ToString>(kind: ErrorKind, description: &S) -> Self

Creates a new Error with the given description.

Do not use this for wrapping std::error::Error; use Error::with_source() instead.

pub fn with_source<E: Error + Send + Sync + 'static>( kind: ErrorKind, msg: String, source: E, ) -> Self

Creates a new Error whose std::error::Error::source() is source.

msg should describe the operation which failed so as to give context for how source is a meaningful error. For example, if source is a std::io::Error from trying to read a file, then msg should include the path of the file and why the file is relevant.

pub fn kind(&self) -> ErrorKind

Obtain the inner ErrorKind for this error

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.

The specific type of the returned error should not be considered part of the stable interface of this crate; prefer to use this only for displaying error information.

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.
