NativeUnionVal class
Represents a union value for Soroban contract specifications. Used when passing union type values to contract functions.
Union types in Stellar contracts can have two forms:
- Void case - just a tag name (e.g., "Success", "Error")
- Tuple case - a tag name with associated values (e.g., "Data" with values
["field1", "field2"])
Constructors
- NativeUnionVal(String tag, {List? values})
-
Creates a union value with the specified tag and optional values
const
- NativeUnionVal.tupleCase(String tag, List? values)
-
Creates a tuple union case with associated values
const
- NativeUnionVal.voidCase(String tag)
-
Creates a void union case (no associated values)
