Struct LiveBudget 

pub struct LiveBudget { /* private fields */ }

Mutable runtime state tracking the current point budget.

One LiveBudget should be shared across all requests to the same plugin endpoint, wrapped in Arc<Mutex<LiveBudget>> to serialise updates.

impl LiveBudget

pub fn new(config: &CostThrottleConfig) -> Self

Create a new budget initialised from config defaults.

pub fn update_from_response(&mut self, throttle_status: &Value)

Update the budget from a throttle-status object.

The JSON path is extensions.cost.throttleStatus in the GraphQL response body.

use serde_json::json;
use stygian_graph::adapters::graphql_throttle::{CostThrottleConfig, LiveBudget};

let mut budget = LiveBudget::new(&config);

let status = json!({
    "maximumAvailable": 10000.0,
    "currentlyAvailable": 4200.0,
    "restoreRate": 500.0,
});
budget.update_from_response(&status);
