Struct versio::errors::Error[−][src]

pub struct Error(pub ErrorKind, _);

Expand description

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().

Tuple Fields

0: ErrorKind

The kind of the error.
