Struct UsageSnapshot

    pub notes: Vec<String>,
}

Normalized, secret-free usage observation for one (provider, account).

Fields

schema_version: u32

provider: String

Canonical OAuth provider id (anthropic, openai-codex, kimi-code, xai-auth).

account: String

default or the account label.

observed_at: u64

Epoch ms when the body was received; authoritative for staleness.

plan: Option<String>

limit_reached: Option<bool>

Provider-asserted overall exhaustion flag (Codex rate_limit.limit_reached).

spend_control_reached: Option<bool>

Workspace/account spend control tripped (Codex spend_control.reached). Some(true) blocks subscribed availability exactly like limit_reached.

windows: Vec<UsageWindow>

model_availability: Vec<ModelAvailability>

credits: Option<CreditBalance>

banked_resets: Option<BankedResets>

identity_prefix: Option<String>

First 8 chars of a provider account id when the response carries one.

seat_fingerprint: Option<String>

Opaque full seat identity paired with the bearer used for this reading. Currently supplied by the Codex adapter; absent on older brokers.

notes: Vec<String>

Fixed-vocabulary parse notes (never raw keys or values).

Implementations

impl UsageSnapshot

pub fn is_stale(&self, now_ms: u64, max_age_ms: u64) -> bool

Observation older than max_age_ms (or from the future) is stale. Stale readings are never capacity.

pub fn window(&self, id: &str) -> Option<&UsageWindow>

pub fn account_windows(&self) -> impl Iterator<Item = &UsageWindow>

pub fn longest_account_window(&self) -> Option<&UsageWindow>

The account window with the longest known duration (e.g. weekly). Windows with unknown duration sort last.

pub fn has_proven_capacity(&self, now_ms: u64, max_age_ms: u64) -> bool

Fresh, provider did not flag exhaustion or a tripped spend control, at least one account window, and every account window has a valid percent below 100.

pub fn model_availability_for(&self, model: &str) -> Option<&ModelAvailability>

Availability entry for a requested model id, if the provider reported one.

pub fn has_proven_capacity_for_model( &self, model: &str, now_ms: u64, max_age_ms: u64, ) -> bool

Model-aware capacity: account capacity AND, when the provider reported anything about this model, that entry must be Available. A gated model (model_usage.available == false, Astra-style) or an exhausted model window rejects even when the generic quota is nearly unused. Models the provider did not mention fall back to account capacity.

pub fn earliest_reset_at(&self) -> Option<u64>

Earliest reset across all windows and model availability entries.

Trait Implementations

impl Clone for UsageSnapshot

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsageSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UsageSnapshot

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

where __D: Deserializer<'de>,

Inequality operator !=.

impl Serialize for UsageSnapshot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
