macro.
Associated Types
type ErrorKind
Associated kind type.
Required Methods
fn from_kind(kind: Self::ErrorKind) -> Self where
Self: Sized,
Self: Sized,
Constructs an error from a kind, and generates a backtrace.
fn with_chain<E, K>(error: E, kind: K) -> Self where
Self: Sized,
E: Error + Send + 'static,
K: Into<Self::ErrorKind>,
Self: Sized,
E: Error + Send + 'static,
K: Into<Self::ErrorKind>,
Constructs a chained error from another error and a kind, and generates a backtrace.
fn kind(&self) -> &Self::ErrorKind
Returns the kind of the error.
fn iter(&self) -> ErrorChainIter
Iterates over the error chain.
fn backtrace(&self) -> Option<&Backtrace>
Returns the backtrace associated with this error.
Provided Methods
fn display<'a>(&'a self) -> Display<'a, Self>
Returns an object which implements Display for printing the full
context of this error.
The full cause chain and backtrace, if present, will be printed.
