Create Variable

Define and initialize a new variable in your function stack.
Variables can hold static values, derive from existing variables, or be transformed using actions.

Config

• Value: The initial value of the variable. It can be a raw input (e.g. a string, number) or another variable.
• Action: An optional transformation to apply before assigning the final value to the variable.

Example 1: Create a Simple Variable

In this example, we create a variable called personName with a raw string value "rebaz".

---

Example 2: Change Variable Type

We create a variable named personAge and provide the value 30 as an Int.

---

Example 3: Transform Value with Action

Here, a variable called transformedRes is created with value 2025, with type of Int64.
Then the action To Result is applied to wrap the value as a Result.

Available actions include:

• Force Unwrap: Forcefully unwrap the value (panics if invalid).
• To Optional: Wraps the value as an optional.
• To Pointer: Converts to a pointer (used when passing by value is not enough). in most cases, you don't need this.
• To Result: Wraps the value in a Result, containing either data or error.

Example 4: Create from Existing Variable

Create a new variable name2 using the value from an existing variable personName.

---

Example 5: Create from Existing Variable + Transform

Create a variable age2 from existing personAge and apply the To Optional transformation.

---

Example 6: Extract from Struct Field

Extract a field from a struct into a new variable.
In this case, type is selected from a nested field within a previously created struct variable.

---

Example 7: Create a Late Variable

Declare a variable without assigning an initial value — useful when the value will be set later (e.g. inside a loop or condition block).

Set the variable name and type, then in the action selector, choose Change To Late Var.
