Struct ComponentInstance 

pub struct ComponentInstance {
    pub id: String,
    pub component: String,
    pub recursive_reentrance: bool,
}

Component instance

Fields

id: String

Instance ID

component: String

Referenced component

recursive_reentrance: bool

Allow recursive reentrance into this instance.

The Component Model spec traps when call_might_be_recursive detects that a component instance is already on the call stack (Concurrency.md). After fusion (e.g. via meld), the caller and callee share the same instance, making cross-component calls appear reentrant even though the original components were distinct.

When true, the AOT-generated canonical ABI entry sequence skips the reentrancy guard for calls into this instance. This is an opt-in extension ahead of the spec’s planned recursive effect on function types.

Default: false (spec-compliant trapping behavior).
