    Unsupported constructs

    The compiler reports unsupported constructs during trigora dev or deployment, before an Execution can start.

    Ordinary computation between durable operations is supported, including one-level destructuring. See Supported language semantics for the complete supported language inventory.

    Unsupported syntax

    Section titled “Unsupported syntax”
    • A rest parameter, *args, a binding pattern, or a second program entry. Entry parameters and defaults that do compile are on Programs.
    • TypeScript this, classes, prototypes, generators, and async arrows.
    • A helper or closure frame that performs a durable operation. Durable operations stay in the program entry. A closure value may live across a wait.
    • Classes, traits, macros, and async helpers in Rust. See Rust.
    • Stored promises, spread or dynamic arrays inside Promise.all / Promise.race, .then, Promise.any, and Promise.allSettled.
    • A bare, assigned, stored, pre-awaited, starred, listed, or nested gather / race, and asyncio.gather, asyncio.wait, and asyncio.FIRST_COMPLETED. The forms that compile are on Structured concurrency.
    • Unnamed effects. effect requires a non-empty string key.
    • Non-literal effect keys and event names.
    • Executing the Program module as a normal script.

    Compile-time behavior

    Section titled “Compile-time behavior”

    Unsupported constructs produce a compile error; Trigora does not substitute a different execution or recovery model. Promise.any and Promise.allSettled are not supported. Support for additional authoring languages is planned.
