Trait Implementations§

Source§

impl<T: StatementNode<Scope = Scope>, Scope> Expr for Block<T, Scope>

Source§

const COMPLEXITY: usize

Trivial measure of complexity: a variable is 1, an operation is 1, a binary op is 2, a conditional is 3, etc.
Source§

type Return = <T as Expr>::Return

Return type of eval (if not an error).
Source§

type Scope = Scope

Data structure holding all variables in scope.
Source§

fn eval(&self, scope: &mut Self::Scope) -> Self::Return

Find and return a mutation, if any, that passes the given test suite. Evaluate as if running the original function.
