Module: hyperliquid/preflight

Source: hyperliquid/preflight.rs

Fail-closed market-context checks for authenticated execution.

This module is deliberately transport-free: a caller must bind an order to a specific, fresh, finite market observation before it is signed. A wall clock timestamp alone is not evidence that a quote is usable for an order.

Structs

pub struct MarketSnapshot

#![allow(unused)]
fn main() {
pub struct MarketSnapshot {
    pub symbol: String,
    pub observed_at: DateTime < Utc >,
    pub reference_price: f64,
};
}

Immutable quote evidence captured at the decision boundary.

pub struct MarketContextPolicy

#![allow(unused)]
fn main() {
pub struct MarketContextPolicy {
    pub max_age: Duration,
    pub max_limit_deviation_bps: u32,
};
}

Explicit bounds for accepting a market observation for execution.
