Enum AnswerPromptError 

#[non_exhaustive]
pub enum AnswerPromptError {
    ClosedInput,
    DroppedRequest,
    UnscriptedPrompt,
    UnusableTerminal {
        source: Error,
    },
}

The error that ends a prompt without an answer from the user

The presenter reports this error through the Reply of a request. No variant is an answer, so a command must not treat one as a yes, a no, or a default.

A later release can add variants. Match with a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ClosedInput

The user closed the input instead of answering

On a terminal, Ctrl+D closes the input.

DroppedRequest

The presenter dropped the request without an answer

A presenter that cannot ask a user drops every request.

UnscriptedPrompt

The script of a test holds no answer that fits the prompt

A ScriptedUser reports this when its script has ended, and when the next answer is for another kind of prompt.

UnusableTerminal

The terminal could not show the prompt or read the answer

Fields

source: Error

The cause of the failure
