Struct ethcore::error::BlockImportError

pub struct BlockImportError(pub BlockImportErrorKind, _);

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().

Methods

impl BlockImportError

pub fn from_kind(kind: BlockImportErrorKind) -> BlockImportError

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

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

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 ) -> BlockImportError where     K: Into<BlockImportErrorKind>,

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

pub fn kind(&self) -> &BlockImportErrorKind

Returns the kind of the error.

Important traits for Iter<'a>

impl<'a> Iterator for Iter<'a> type Item = &'a (Error + 'a);

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) -> BlockImportError where     F: FnOnce() -> EK,     EK: Into<BlockImportErrorKind>,

Extends the error chain with a new entry.

pub fn description(&self) -> &str

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