Expand description
This trait is implemented on all the errors generated by the error_chain
macro.
Associated Types
Required methods
fn from_kind(kind: Self::ErrorKind) -> Self where
Self: Sized,
[src]
fn from_kind(kind: Self::ErrorKind) -> Self where
Self: Sized,
[src]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>,
[src]
fn with_chain<E, K>(error: E, kind: K) -> Self where
Self: Sized,
E: Error + Send + 'static,
K: Into<Self::ErrorKind>,
[src]Constructs a chained error from another error and a kind, and generates a backtrace.
Provided methods
fn display_chain<'a>(&'a self) -> DisplayChain<'a, Self>
[src]
fn display_chain<'a>(&'a self) -> DisplayChain<'a, Self>
[src]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.
