Trait fasteval2::evalns::EvalNamespace

pub trait EvalNamespace {
    fn lookup(
        &mut self,
        name: &str,
        args: Vec<f64>,
        keybuf: &mut String
    ) -> Option<f64>;
}

All fasteval Namespaces must implement the EvalNamespace trait.

Required Methods

    &mut self,
    name: &str,
    args: Vec<f64>,
    keybuf: &mut String
) -> Option<f64>

Perform a variable/function lookup.

May return cached values.
