Struct ComponentFunction 

pub struct ComponentFunction {
    pub name: String,
    pub span_start: u32,
    pub kind: ComponentFunctionKind,
    pub is_exported: bool,
    pub has_unharvestable_props: bool,
    pub uses_clone_element: bool,
    pub renders_provider: bool,
    pub has_children_as_function: bool,
    pub is_pure_passthrough: bool,
}

An identified React component: a function/arrow whose body returns JSX. Captured by visit_jsx_element’s enclosing-component tracking. The unused-component-prop (React arm) and complexity-fold phases consume this; the abstain flags keep zero-FP on the cases ADR-001 cannot resolve.

Fields

name: String

The component name (the binding or declaration identifier).

span_start: u32

Start byte offset of the component definition (anchors findings).

kind: ComponentFunctionKind

The syntactic shape of the definition.

is_exported: bool

Whether the component is exported from its module (a named export, a export default, or re-exported in the same module). Public-API components abstain in the prop phase.

has_unharvestable_props: bool

true when the component’s props are not statically harvestable: a rest/spread in the signature ({ ...rest }), props passed wholesale to a hook/helper, or a forwardRef / memo wrapper whose props come from an imported interface generic fallow cannot resolve (ADR-001). The prop phase abstains on the whole component when set.

uses_clone_element: bool

true when the component body calls cloneElement / React.cloneElement. cloneElement injects props by reflection, so the static forward-set is incomplete; the prop-drilling phase abstains on any chain through this component (ADR-001, zero-FP).

renders_provider: bool

true when the component renders a *.Provider member-expression tag (<FooContext.Provider>). A context provider in the subtree means the drilling may be a deliberate non-context choice (or the prop is about to be provided); the prop-drilling phase downgrades/abstains.

has_children_as_function: bool

true when the component passes a function as a child render value (render-props / children-as-function: <Foo>{() => ...}</Foo> or <Foo render={() => ...}/>). The forwarded shape is dynamic; the prop-drilling phase abstains on chains through this component.

is_pure_passthrough: bool

true when the component body is pure structural indirection: a single statement returning exactly one capitalized/member-expression JSX element (no host wrapper, no extra children, optionally a fragment wrapping a single element) that forwards props via a bare spread of the component’s own props binding / rest local (<Child {...props}/>), with NO named attributes alongside the spread and NO self-render. The cross-component thin-wrapper phase joins this with hook-density / cyclomatic checks and the resolved single render edge to flag a component that is a candidate for inlining. Computed from the component’s own AST only, so it caches byte-identity-safe (ADR-001).
