Struct udi::Error

pub struct Error(pub ErrorKind, pub State);

The Error type.

This struct is made of three things:

• ErrorKind which is used to determine the type of the error.
• a backtrace, generated when the error is created.
• an error chain, used for the implementation of Error::cause().

Methods

impl Error

pub fn from_kind(kind: ErrorKind) -> Self

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

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

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

pub fn with_boxed_chain<__K>(error: Box<Error + Send>, kind: __K) -> Error where     __K: Into<ErrorKind>,

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

pub fn kind(&self) -> &ErrorKind

Returns the kind of the error.

pub fn iter(&self) -> Iter

Iterates over the error chain.

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

Returns the backtrace associated with this error.

pub fn chain_err<__F, __EK>(self, error: __F) -> Self where     __F: FnOnce() -> __EK,     __EK: Into<ErrorKind>,

Extends the error chain with a new entry.

Methods from Deref<Target = ErrorKind>

pub fn description(&self) -> &str

A string describing the error kind.
