Struct Function 

pub struct Function {
    pub args: Option<Vec<Value>>,
    pub name: Option<String>,
    pub options: Option<HashMap<String, Value>>,
}

Represents an unevaluated scalar expression. For example, the expression like(user_name, "%alice%") is represented as: name: "like" args { field_reference: "user_name" } args { string_value: "%alice%" }

This type is not used in any activity, and only used as part of another schema.

Fields

args: Option<Vec<Value>>

Optional. Ordered list of arguments the given function expects.

name: Option<String>

Required. The name of the function to evaluate. Requires: * must be in snake case (lower case with underscore separator).

options: Option<HashMap<String, Value>>

Optional. Optional named arguments that certain functions may support.
