Tuple Fields

0: ErrorKind

Implementations

impl Error

pub fn for_kind<E>(kind: ErrorKind) -> impl FnOnce(E) -> Selfwhere
    E: 'static + Send + StdError,

Return a closure that creates a new Error from the given ErrorKind. Particularly useful with map_err:

use bellhop::hooks::{Error, ErrorKind};

let value: i32 = "55"
        .parse()
        .map_err(Error::for_kind(ErrorKind::msg("unable to parse")))
        .unwrap();

pub fn new<E>(kind: ErrorKind, cause: E) -> Selfwhere
    E: 'static + Send + StdError,

Create a new Error with the given kind and cause.

pub fn with_msg<S: Into<String>>(s: S) -> Self

Shortcut for creating an Error with ErrorKind::Msg and no cause.

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 cause(&self) -> Option<&dyn StdError>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

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 provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
