Detailed Description

A base error class.

It implements the cause method for all other builtin error types which have a cause to derived from.

Constructor & Destructor Documentation

error_with_cause()

errors::impl::error_with_cause::error_with_cause ( error_ptr && cause, source_location loc )

inline

Constructor with source_location.

Parameters

loc	The source location.
cause	The cause of the error.

Member Function Documentation

cause() [1/2]

error_ptr errors::impl::error_with_cause::cause ( ) &&

inlineoverridevirtualnoexcept

Transfer the ownership of cause of this error, if any.

Returns

A smart pointer holds the cause of current error, or a nullptr if there is no cause

This method is used to transfer the ownership of the cause, use with caution.

Implements errors::error.

cause() [2/2]

const error_ptr & errors::impl::error_with_cause::cause ( ) const &

inlineoverridevirtualnoexcept

Get cause of this error, if any.

Returns

Reference to a smart pointer which holds the cause of current error, or a nullptr if there is no cause.

Implements errors::error.
