Enum GapMode 

#[non_exhaustive]
pub enum GapMode {
    Ok,
    Fail,
}

How the server should handle gaps in the batch sequence.

A gap means one or more messages in the batch were lost in transit between the client and the stream leader (e.g. due to buffer drops under load).

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.

Ok

Allow gaps — the batch continues and the server informs the client via a gap event. Use this when some message loss is acceptable (metrics, telemetry).

Fail

Fail the batch on the first gap. Use this when in-order, gap-free delivery is required (object store chunks, ordered events). Default.

Trait Implementations

impl Clone for GapMode

fn clone(&self) -> GapMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GapMode

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

Formats the value using the given formatter.

impl Default for GapMode

fn default() -> GapMode

Returns the “default value” for a type.

impl PartialEq for GapMode

fn eq(&self, other: &GapMode) -> 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.

impl Copy for GapMode

impl Eq for GapMode
