Append refusal; every variant leaves entries and watermarks unchanged.

Variants

LabelTooLong

A label exceeded its configured byte ceiling.

Fields

label: Label

Rejected field.

actual_bytes: usize

Supplied UTF-8 byte length.

max_bytes: usize

Configured ceiling.

TimestampRegressed

The timestamp is older than the last admitted append, even after pruning.

Fields

previous: u64

Last admitted timestamp.

current: u64

Rejected timestamp.

SequenceExhausted

All sequence identities have been issued for this log instance.

TextBudgetExceeded

This row’s retained text cannot fit even in an otherwise empty log.

Fields

required_bytes: u128

Required message/source/topic bytes after message truncation.

max_bytes: usize

Configured total retained-text ceiling.

Trait Implementations

impl Clone for AppendError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AppendError

impl Debug for AppendError

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

Formats the value using the given formatter.

impl Display for AppendError

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

Formats the value using the given formatter.

impl Eq for AppendError

impl Error for AppendError

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 AppendError

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

Equality operator ==.

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

Inequality operator !=.
