Struct Stage 

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

A single operation within a pipeline. A stage is made up of a unique name, and a list of arguments. The exact number of arguments & types is dependent on the stage type. To give an example, the stage filter(state = "MD") would be encoded as: name: "filter" args { function_value { name: "eq" args { field_reference_value: "state" } args { string_value: "MD" } } } See public documentation for the full list.

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 stage expects.

name: Option<String>

Required. The name of the stage 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.
