The Error type.
This tuple struct is made of two elements:
- an
ErrorKind
which is used to determine the type of the error.
- An internal
State
, not meant for direct use outside of error_chain
internals, containing:
- a backtrace, generated when the error is created.
- an error chain, used for the implementation of
Error::cause()
.
Constructs an error from a kind, and generates a backtrace.
Constructs a chained error from another error and a kind, and generates a backtrace.
Construct a chained error from another boxed error and a kind, and generates a backtrace
Returns the kind of the error.
Iterates over the error chain.
Returns the backtrace associated with this error.
Extends the error chain with a new entry.
A string describing the error kind.
