Struct BudgetUsageAndLimits 

#[non_exhaustive]
pub struct BudgetUsageAndLimits {
    pub limits: BTreeMap<String, String>,
    pub usage: BTreeMap<String, u64>,
}

Typed snapshot of one budget’s usage + limits map. Returned by crate::engine_backend::EngineBackend::read_budget_usage_and_limits so the scheduler’s BudgetChecker can evaluate hard-limit breaches without reaching at Valkey-shaped HGETs.

limits keys are full field names written by the control-plane (hard:<dimension>, soft:<dimension>, etc.); the scheduler filters on the hard: prefix itself. usage keys are raw dimension names (no prefix) — one entry per dimension currently counting.

Missing limits hash ⇒ both maps empty (return Ok(Self::empty())).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

limits: BTreeMap<String, String>

usage: BTreeMap<String, u64>

Implementations

impl BudgetUsageAndLimits

pub fn new( limits: BTreeMap<String, String>, usage: BTreeMap<String, u64>, ) -> Self

pub fn empty() -> Self

Empty snapshot — returned when the budget’s limits hash is absent. Scheduler treats this as “no limits configured”.

pub fn hard_limits_with_usage(&self) -> impl Iterator<Item = (&str, u64, u64)>

Iterator over hard:<dimension> limits paired with the current usage for that dimension. Usage defaults to 0 for dimensions present in limits but missing from usage.

Trait Implementations

impl Clone for BudgetUsageAndLimits

fn clone(&self) -> BudgetUsageAndLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BudgetUsageAndLimits

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

Formats the value using the given formatter.

impl Default for BudgetUsageAndLimits

fn default() -> BudgetUsageAndLimits

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BudgetUsageAndLimits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BudgetUsageAndLimits

fn eq(&self, other: &BudgetUsageAndLimits) -> 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 Serialize for BudgetUsageAndLimits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
