Struct RCalc

pub struct RCalc { /* private fields */ }

Main calculator struct

Implementations

impl RCalc

pub fn new(rs: Vec<&'static RSeries>) -> Self

Creates a new RCalc with the series used for the R values provided as a vec.

Examples

To create a calculator that will vary over 4 resistors R1, R2, R3 and R4, where we want to draw R1 and R2 from the E24 series, R3 from the E6 series and R4 from the E12 series would be done as follows:

    let rcal = RCalc::new(vec![&E24, &E24, &E6, &E12]);

pub fn e3(count: usize) -> Self

Creates a new RCalc with count resistors drawn from the E3 series.

pub fn e6(count: usize) -> Self

Creates a new RCalc with count resistors drawn from the E6 series.

pub fn e12(count: usize) -> Self

Creates a new RCalc with count resistors drawn from the E12 series.

pub fn e24(count: usize) -> Self

Creates a new RCalc with count resistors drawn from the E24 series.

pub fn combinations(&self) -> u128

Returns the number of combinations of values that exist for the configured resistors and series. This will fairly directly map to the amount of time taken to calculate value combinations.

pub fn calc(&self, f: impl Fn(&RSet) -> Option<f64>) -> Option<RRes>

Given a testing function f thats maps from a set of input resistors to Option<f64> this will calculate the results for the resistors and series configured and return the result as an RRes. f should map combinations that are unsuitable to None and combinations that are suitable to Some(err) where err is a f64 describing how far from perfect the combination is. f is often supplied with the use of the ROpBuilder struct.
