Struct Error

pub struct Error { /* private fields */ }

Implementations

impl Error

pub fn new<E: Into<Box<dyn Error + Send + Sync>>>( kind: ErrorKind, error: Option<E>, ) -> Self

Create a new error.

If this error was caused by another error, specify it as Some(error).

pub fn new_simple(kind: ErrorKind) -> Self

Create a new error without wrapping any other error.

pub fn from_message<M: Into<String>>(kind: ErrorKind, msg: M) -> Self

Create a new error without wrapping any other error.

pub fn kind(&self) -> ErrorKind

Return the kind of this error.

pub fn io_kind(&self) -> ErrorKind

Return the kind of this error when converted into an io::Error.

If the internal error is an io::Error, returns its kind; otherwise, returns the kind it would have if it were converted into an io::Error.

pub fn fatal(&self) -> bool

Indicate whether this error is considered fatal.

An error is fatal if it results in an exit of 2 or higher. A missing revision is not considered fatal, but other errors are.

pub fn exit_status(&self) -> ExitStatus

Return the exit status 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 description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 From<Error> for Error

fn from(error: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Self) -> 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.
