Trait ChainedError 

pub trait ChainedError:

    // Required methods
    fn from_kind(kind: Self::ErrorKind) -> Self

This trait is implemented on all the errors generated by the error_chain macro.

Required 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 with_chain<E, K>(error: E, kind: K) -> Self

where 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
