Struct IOError 

struct IOError {
    err: Error,
}

A std::io::Error.

This type is itself always available, even when the std feature is not enabled. When std is not enabled, a value of this type can never be constructed.

Otherwise, this type is a simple wrapper around std::io::Error. Its purpose is to encapsulate the conditional compilation based on the std feature.

Fields

err: Error
