Why a simple read fanout could not be planned.

Variants

Empty

The read named no targets.

Unroutable

A targeted key resolves to no range of its collection.

Fields

collection: CollectionId

key: Vec<u8>

FanoutNotExplicit

The read would cross owners, but the caller did not explicitly opt into fanout.

Fields

owners: Vec<NodeIdentity>

TargetBudgetExceeded

The request named more targets than the fanout budget permits.

Fields

requested: usize

max: usize

OwnerBudgetExceeded

The plan would contact more owners than the fanout budget permits.

Fields

requested: usize

max: usize

RangeBudgetExceeded

The plan would touch more ranges than the fanout budget permits.

Fields

requested: usize

max: usize

Trait Implementations

impl Clone for ReadFanoutReject

fn clone(&self) -> ReadFanoutReject

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadFanoutReject

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

Formats the value using the given formatter.

impl Display for ReadFanoutReject

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

Formats the value using the given formatter.

impl Eq for ReadFanoutReject

impl Error for ReadFanoutReject

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 ReadFanoutReject

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