Rejection reasons returned by validate_placement.

These are correctness checks, not security checks. Since placement accepts topology spreading only, there is no scheduling primitive here that could place a Pod somewhere it is not otherwise allowed — see the module docs. Each variant carries enough context for the reconciler to render an actionable Ready=False condition on the offending CR.

Most of these are also enforced structurally by the generated CRD schema (maxItems, the topologyKey pattern, value ranges, and an x-kubernetes-validations rule for the minDomains pairing), so they are normally rejected at admission. This validator remains the backstop for clusters running an older CRD revision, and covers the one rule a structural schema cannot express cheaply: uniqueness across rules.

Trait Implementations

impl Debug for PlacementRejection

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

Formats the value using the given formatter.

impl Display for PlacementRejection

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

Formats the value using the given formatter.

impl Error for PlacementRejection

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 PlacementRejection

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