Trait error_chain::ChainedError
[−]
[src]
pub trait ChainedError: Error + Send + 'static {
type ErrorKind;
fn from_kind(kind: Self::ErrorKind) -> Self where Self: Sized;

}This trait is implemented on all the errors generated by the error_chain
macro.
Associated Types
type ErrorKind
Associated kind type.
Required Methods
fn from_kind(kind: Self::ErrorKind) -> Self where Self: Sized
Constructs an error from 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.
