pub struct Arguments(pub Arc<Vec<Value>>);Expand description
An argument extractor that extracts all the arguments passed to a function, resolves their
expressions and returns a vector of Value.
This is useful for functions that accept a variable number of arguments rather than known
arguments and types (for example a sum function).
§Example
sum(1, 2.0, uint(3)) == 5.0use cel_interpreter::extractors::Arguments;
pub fn sum(Arguments(args): Arguments) -> Value {
args.iter().fold(0.0, |acc, val| match val {
Value::Int(x) => *x as f64 + acc,
Value::UInt(x) => *x as f64 + acc,
Value::Float(x) => *x + acc,
_ => acc,
}).into()
