Struct charts::prelude::err::Error

source · [−]

pub struct Error(pub ErrorKind, _);

Expand description

The Error type.

This tuple struct is made of two elements:

an ErrorKind which is used to determine the type of the error.
An internal State, not meant for direct use outside of error_chain internals, containing:
- a backtrace, generated when the error is created.
- an error chain, used for the implementation of Error::cause().

Tuple Fields

0: ErrorKind

The kind of the error.

Implementations

source

impl Error

source

pub fn from_kind(kind: ErrorKind) -> Error

Constructs an error from a kind, and generates a backtrace.

source

pub fn with_chain<E, K>(error: E, kind: K) -> Error where
E: 'static + Error + Send,
K: Into<ErrorKind>,

Constructs a chained error from another error and a kind, and generates a backtrace.

source

pub fn with_boxed_chain<K>(
 error: Box<dyn Error + Send + 'static, Global>,
 kind: K
) -> Error where
 K: Into<ErrorKind>,

Construct a chained error from another boxed error and a kind, and generates a backtrace

source

pub fn kind(&self) -> &ErrorKind

Returns the kind of the error.

source

pub fn iter(&self) -> Iter<'_>ⓘNotable traits for Iter<'a>`impl<'a> Iterator for Iter<'a> type Item = &'a (dyn Error + 'a);`

Iterates over the error chain.

source

pub fn backtrace(&self) -> Option<&Backtrace>

Returns the backtrace associated with this error.

source

pub fn chain_err<F, EK>(self, error: F) -> Error where
F: FnOnce() -> EK,
EK: Into<ErrorKind>,

Extends the error chain with a new entry.

source

pub fn description(&self) -> &str

A short description of the error. This method is identical to Error::description()

source

impl Error

source

pub fn to_pretty(&self) -> String

Multi-line representation of a trace of errors.

See the module-level documentation for more.
