Derive Macro timescale_macros::InterpolatedDataTable

#[derive(InterpolatedDataTable)]
{
    // Attributes available to this derive:
    #[table]
}

Load a csv file into a static data table with support for linearly interpolating data points between the discreet time intervals

This derive macro goes hand and hand with the InterpolatedData derive macro. Data loaded into this table needs to be decorated with the aforementioned InterpolatedData derive macro so that their structure can be available to this macro at build time.

Arguments

This macro requires 2 arguments.

• st describes the structure (that derives InterpolatedData) to represent the timescale data.
• file describes the csv file to read in the timescale data from

Example

See the data in this csv file for context for the following example

use timescale::{InterpolatedData, InterpolatedDataTable};

#[derive(Debug, Lerp, InterpolatedData)]
pub struct RocketEngine {
    #[data(rename = "Thrust (N)")]
    pub thrust: f64,
}

/// The thrust curve of an Estes A8 rocket motor
#[derive(InterpolatedDataTable)]
#[table(file = "../assets/motors/Estes_A8.csv", st = "RocketEngine")]
pub struct EstesA8;

fn main() {
    assert_eq!(EstesA8::get(0.35).thrust, 3.813); // Exact value from data
    assert_eq!(EstesA8::get(0.4).thrust, 3.9468823529411763); // Linear interpolated estimate
    assert_eq!(EstesA8::get(1.0).thrust, 0.0); // Saturated at 0
}
