Enum AeronOfferError 

pub enum AeronOfferError {
    NotConnected,
    BackPressured,
    AdminAction,
    Closed,
    MaxPositionExceeded,
    TooManyParts,
    Error(AeronCError),
}

Typed error for offer / try_claim on a publication.

Aeron returns a negative sentinel instead of a stream position. These are not errno-style codes — -1 here means “not connected”, not a generic error — hence this dedicated type. Use Self::is_retryable to drive retry loops.

Variants

NotConnected

No subscriber is connected (-1). Usually transient: a subscriber may connect later. Retryable.

BackPressured

Flow control or a full term buffer is applying back pressure (-2). Retry after idling. Retryable.

AdminAction

An administrative action (e.g. term rotation) is in progress (-3). Retry immediately. Retryable.

Closed

The publication is closed (-4). Fatal for this handle.

MaxPositionExceeded

The maximum stream position was reached (-5). Fatal: a new publication (new session) is required.

TooManyParts

More than [MAX_OFFER_PARTS] buffers passed to offer_parts — a caller bug, not an Aeron wire error. Fatal (fix the call site).

Error(AeronCError)

Any other negative value (-6 / unexpected). Fatal; inspect the inner AeronCError and Aeron::errmsg() for detail.

Implementations

impl AeronOfferError

pub fn from_position(position: i64) -> Result<i64, Self>

Maps a raw offer/try_claim return to Ok(position) or a typed error.

pub fn is_retryable(&self) -> bool

A retry (possibly after idling / waiting for a subscriber) can succeed.

pub fn is_fatal(&self) -> bool

The publication will never accept this offer again; recreate or give up.

Trait Implementations

impl Clone for AeronOfferError

fn clone(&self) -> AeronOfferError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AeronOfferError

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

Formats the value using the given formatter.

impl Display for AeronOfferError

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

Formats the value using the given formatter.

impl Eq for AeronOfferError

impl Error for AeronOfferError

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 PartialEq for AeronOfferError

fn eq(&self, other: &AeronOfferError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
