enum CallModifier [src]

This data structure is used by the Zig language code generation and therefore must be kept in sync with the compiler implementation.

Fields

autoEquivalent to function call syntax.

async_kwEquivalent to async keyword used with function call syntax.

never_tailPrevents tail call optimization. This guarantees that the return address will point to the callsite, as opposed to the callsite's callsite. If the call is otherwise required to be tail-called or inlined, a compile error is emitted instead.

never_inlineGuarantees that the call will not be inlined. If the call is otherwise required to be inlined, a compile error is emitted instead.

no_asyncAsserts that the function call will not suspend. This allows a non-async function to call an async function.

always_tailGuarantees that the call will be generated with tail call optimization. If this is not possible, a compile error is emitted instead.

always_inlineGuarantees that the call will be inlined at the callsite. If this is not possible, a compile error is emitted instead.

compile_timeEvaluates the call at compile-time. If the call cannot be completed at compile-time, a compile error is emitted instead.
