#[non_exhaustive]
pub enum PollAnswersError {
    TooManyValues,
    NotEnoughValues,
}

Available on crate features events and unstable-msc3381 only.

Expand description

An error encountered when trying to convert to a PollAnswers.

Variants (Non-exhaustive)

This enum is marked as 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.

`TooManyValues`

There are more than PollAnswers::MAX_LENGTH values.

`NotEnoughValues`

There are less that PollAnswers::MIN_LENGTH values.
