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