Why a budget was refused.

Variants

Oversubscribed

Declared peak shares exceed the quota floor.

Fields

quota: f64

The fractional quota (cores).

floor: u64

floor(quota) the integer shares must sum to.

declared: u64

The declared sum that exceeded it.

QuotaTooSmallForPinnedRoles

Fractional quota below the pinned-role floor (H+A+R+M+2).

Fields

quota: f64

The fractional quota (cores).

required: u64

The minimum usable quota.

TooFewSolverCpus

Solver share derives below the minimum.

Fields

solver: u64

The derived/declared Solver share.

min: u64

MIN_SOLVER_CPUS.

BelowHostFloor

Fractional quota below the 2-core host floor (FLEETFLOOR FF-T2: one core for I/O work, one core for solve work) — no binding can host the fleet there, forced or not.

Fields

quota: f64

The fractional quota (cores).

IoWorkersOutOfBounds

A runtime.io_workers override the resolved plan cannot honor (FF-T2): below the ambient floor (A >= 1) on the pinned binding, or off the serial binding\u0027s exactly-one ambient I/O lane. Refused with a hint, never a silent clamp.

Fields

requested: u64

The requested override.

binding: &'static str

The binding the plan resolved (the label).

Implementations

impl BudgetError

pub const fn name(&self) -> &'static str

The typed variant NAME (the closed, greppable refusal vocabulary). runtime_status()’s tier_refused string names the family the plan fell from (FF-T5 addendum, 452GZC); the Display wording stays the operator sentence with the quota, the floor, and the hint.

Trait Implementations

impl Clone for BudgetError

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 BudgetError

impl Debug for BudgetError

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

Formats the value using the given formatter.

impl Display for BudgetError

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

Formats the value using the given formatter.

impl Error for BudgetError

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
