Struct FundingRate 

pub struct FundingRate {
    pub symbol: String,
    pub rate: f64,
    pub timestamp_ms: u64,
    pub annualized: f64,
}

A single perpetual-futures funding rate observation.

Funding rates are typically settled every 8 hours (3× per day). The annualized field converts the period rate to an annual rate.

Fields

symbol: String

Trading pair symbol (e.g. "BTCUSDT").

rate: f64

Raw funding rate for one 8-hour period (e.g. 0.0001 = 0.01%).

timestamp_ms: u64

Unix timestamp in milliseconds of this funding observation.

annualized: f64

Annualized funding rate = rate × 3 × 365.

Implementations

impl FundingRate

pub fn new(symbol: impl Into<String>, rate: f64, timestamp_ms: u64) -> Self

Construct a new FundingRate, computing annualized automatically.

Arguments

• symbol - Trading pair identifier.
• rate - Raw 8-hour period rate.
• timestamp_ms - Observation time in milliseconds since Unix epoch.
