Enum GroupAppDataError 

pub enum GroupAppDataError<StorageError: Error> {
    Propose(ProposalError<StorageError>),
    CreateCommit(CreateCommitError),
    StageCommit(CommitBuilderStageError<StorageError>),
    ApplyPayload(ComponentSourceError),
    Upkeep(Box<GroupError>),
}

Errors surfaced by [stage_app_data_propose_and_commit].

Wrapped into GroupError via the #[from] impl on GroupError::AppDataCommit so the structured source is preserved at the call site (no string-flattening). The pub(crate) visibility matches the helper itself; the variant is only re-exported through the public GroupError enum.

Variants

Propose(ProposalError<StorageError>)

propose_app_data_update(…) failed when staging the standalone proposal that precedes the commit.

CreateCommit(CreateCommitError)

commit_builder().load_psks(…).build(…) failed.

StageCommit(CommitBuilderStageError<StorageError>)

stage_commit(provider) failed (storage / signature / staging error).

ApplyPayload(ComponentSourceError)

apply_app_data_update_payload failed while pre-computing the new dict value the commit builder hands to OpenMLS. The most common cause is a mismatch between the sender’s idea of the current dict state and the receiver’s, which would surface as a confirmation tag mismatch on the wire if it ever escaped.

Upkeep(Box<GroupError>)

Computing the removed-member cleanup for a swept removal failed, or the commit would grow the dictionary past its total.

Trait Implementations

impl<StorageError: Debug + Error> Debug for GroupAppDataError<StorageError>

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

Formats the value using the given formatter.

impl<StorageError: Error> Display for GroupAppDataError<StorageError>

where ProposalError<StorageError>: Display, CommitBuilderStageError<StorageError>: Display,

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

Formats the value using the given formatter.

impl<StorageError: Error> Error for GroupAppDataError<StorageError>

where ProposalError<StorageError>: Error + 'static, CommitBuilderStageError<StorageError>: Error + 'static, Self: Debug + Display,

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>)

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

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

impl<StorageError: Error> From<CommitBuilderStageError<StorageError>> for GroupAppDataError<StorageError>

fn from(source: CommitBuilderStageError<StorageError>) -> Self

Converts to this type from the input type.

impl<StorageError: Error> From<ComponentSourceError> for GroupAppDataError<StorageError>

fn from(source: ComponentSourceError) -> Self

Converts to this type from the input type.

impl<StorageError: Error> From<CreateCommitError> for GroupAppDataError<StorageError>

fn from(source: CreateCommitError) -> Self

Converts to this type from the input type.

impl From<GroupAppDataError<SqlKeyStoreError>> for GroupError

fn from(source: GroupAppDataError<SqlKeyStoreError>) -> Self

Converts to this type from the input type.

impl<StorageError: Error> From<ProposalError<StorageError>> for GroupAppDataError<StorageError>

fn from(source: ProposalError<StorageError>) -> Self

impl RetryableError for GroupAppDataError<SqlKeyStoreError>

fn is_retryable(&self) -> bool

fn rate_limit_delay(&self) -> Option<Duration>

The least time to wait before a retry, when the error says so. A rate-limit rejection carries one; [retry_async!] never retries sooner.
