Enum GroupError 

#[non_exhaustive]
pub enum GroupError {
    Iq(IqError),
    Mex(MexError),
    InvalidRequest(String),
    DescriptionConflict,
    Internal(Error),
}

Error returned by group operations (metadata queries, participant and settings mutations, invites, profile pictures).

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.

Iq(IqError)

A w:g2 IQ to the server failed (transport, timeout, server rejection).

Mex(MexError)

A MEX (GraphQL) group-property mutation failed.

InvalidRequest(String)

The request was malformed (e.g. empty invite code, batch over the limit, expired V4 invite, non-group JID where one is required).

DescriptionConflict

The server refused a description update because the prev token no longer matches the group’s current description: another device changed it first. Distinct from a permission refusal, so a caller can re-read the description and retry instead of giving up.

Internal(Error)

Catch-all for internal failures (LID/PN resolution, the protocol-message send path behind update_member_label, cache plumbing).

Trait Implementations

impl Debug for GroupError

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

Formats the value using the given formatter.

impl Display for GroupError

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

Formats the value using the given formatter.

impl Error for GroupError

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

Returns the lower-level source of this error, if any.

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>)
