Struct GraphBudget 

pub struct GraphBudget<'a> {
    pub max_calls: u32,
    pub max_bytes_fetched: u64,
    pub max_nodes: u32,
    pub deadline: Box<dyn Fn() -> SleepFuture + 'a>,
    pub half_deadline: Option<Box<dyn Fn() -> SleepFuture + 'a>>,
}

The per-graph budget of a GASPSync (bsv-low #555, Engine::set_graph_budget). Setting one turns deferral ON for that sync.

Fields

max_calls: u32

Calls one graph may make in one pass (DEFAULT_GRAPH_BUDGET_CALLS).

max_bytes_fetched: u64

Bytes one graph may be served in one pass (DEFAULT_GRAPH_BUDGET_BYTES, bsv-low #586). Reached, the graph is DEFERRED as at max_calls (reason bytes): never dropped, never refused.

max_nodes: u32

Nodes one graph may append in one pass (DEFAULT_GRAPH_BUDGET_NODES, bsv-low #586). Reached, the graph is deferred (reason nodes).

deadline: Box<dyn Fn() -> SleepFuture + 'a>

A fresh deadline for ONE graph’s pass (DEFAULT_GRAPH_BUDGET_MS).

half_deadline: Option<Box<dyn Fn() -> SleepFuture + 'a>>

A fresh deadline for HALF of it (the delta-2 fold’s D2-L1): a FRESH walk that faults once this fell due, or after half its calls, has paid for a record and keeps one. None: the calls alone decide.
