Enum PollError 

#[non_exhaustive]
pub enum PollError {
    Send(SendError),
    InvalidPoll(String),
    NotLoggedIn,
    Crypto(Error),
}

Errors from poll operations (creation, voting, and vote decryption).

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.

Send(SendError)

Sending the poll/vote stanza failed (embeds the send path error).

InvalidPoll(String)

The poll definition is invalid (option count, duplicate names, bad quiz index, selectable count out of range).

NotLoggedIn

The client is not logged in, so the voter identity can’t be resolved.

Crypto(Error)

Vote decryption/encryption (HKDF/GCM) failed.

Trait Implementations

impl Debug for PollError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PollError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

impl Error for PollError

fn source(&self) -> Option<&(dyn Error + 'static)>

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<SendError> for PollError

fn from(source: SendError) -> Self

Converts to this type from the input type.
