// Library Definition (Imaginary - For Demonstration Purposes)
// =============================================================================

// Assume a library named `myimportlib` with an exported type `ImportedUDT`
// and an exported enum `ExportedEnum` is defined elsewhere.

// @type ImportedUDT, all library code require exported types and enums to have `export` defined
// @field field1 int,defval = 10
// @field field2 string,defval = "hello"
export type ImportedUDT
    int field1 = 10

// @field VALUE1
// @field VALUE2
