Trait RootFunctions 

pub trait RootFunctions {
    // Required methods
    fn count(&self) -> usize;
    fn evaluate(
        &self,
        time: f64,
        state: &[f64],
        output: &mut [f64],
    ) -> Result<(), Diagnostic>;
}

Zero-crossing actions used only to propose candidate event instants.

A backend may localize the first sign change, but it does not decide event direction, simultaneous grouping, priority, or reset commit semantics.

Required Methods

fn count(&self) -> usize

Signature links:countusize

Number of scalar root functions.

fn evaluate( &self, time: f64, state: &[f64], output: &mut [f64], ) -> Result<(), Diagnostic>

Signature links:evaluatef64f64f64Result()Diagnostic

Evaluate every root function at one state/time point.

Errors

Returns a stable diagnostic when root evaluation fails.
