Struct EvalContext

pub struct EvalContext {
    pub names: HashMap<String, Set>,
    pub fns: HashMap<String, Box<dyn Fn(&str, &Repo, &[Expr], &Context) -> Result<Set>>>,
}

Extra context for eval. It can define customized aliases.

Fields

names: HashMap<String, Set>

Extra pre-calculated sets. For example, if “foo” is defined here, “foo + x” will use the defined “foo” set.

fns: HashMap<String, Box<dyn Fn(&str, &Repo, &[Expr], &Context) -> Result<Set>>>

Extra functions. For example, if “foo” is defined here, “foo(x)” will use the “foo” function.
