Struct NamespaceQuota 

pub struct NamespaceQuota {
    pub namespace: String,
    pub limit_bytes: u64,
    pub used_bytes: Arc<AtomicU64>,
    pub policy: QuotaPolicy,
    pub block_count: Arc<AtomicU64>,
}

Quota state for a single namespace.

Fields

namespace: String

Identifier for this namespace.

limit_bytes: u64

Maximum bytes allowed (only meaningful for HardLimit / SoftLimit).

used_bytes: Arc<AtomicU64>

Currently consumed bytes (atomic, shared across threads).

policy: QuotaPolicy

Enforcement policy.

block_count: Arc<AtomicU64>

Number of stored blocks (atomic, shared across threads).

Implementations

impl NamespaceQuota

pub fn new(namespace: String, limit_bytes: u64, policy: QuotaPolicy) -> Self

Create a new NamespaceQuota.

pub fn available_bytes(&self) -> u64

Returns how many bytes are still available before the limit is reached.

Uses saturating subtraction, so returns 0 when already over limit.

pub fn usage_ratio(&self) -> f64

Returns the fraction of the limit currently used (range [0.0, ∞)).

Returns 0.0 when limit_bytes is 0 to avoid division by zero.

pub fn is_over_soft_threshold(&self, threshold: f64) -> bool

Returns true when usage_ratio() exceeds threshold.
