Struct HookUse 

pub struct HookUse {
    pub kind: HookUseKind,
    pub dep_array_arity: Option<u32>,
    pub span_start: u32,
    pub component: String,
}

A React hook call site inside a component. Consumed by the complexity-fold phase (hook density) and surfaced as descriptive hotspot context.

Fields

kind: HookUseKind

The hook kind.

dep_array_arity: Option<u32>

The dependency-array arity, recorded ONLY when a literal array is present at the dependency-array position ([a, b] -> Some(2), [] -> Some(0)). None when the call has no dependency array argument or the argument is not a literal array (ADR-001: do not guess).

span_start: u32

Start byte offset of the hook call (anchors findings).

component: String

The enclosing component name (the top of the visitor’s component stack when the hook call was recorded). Lets the descriptive per-component hook summary attribute hooks exactly even when a file declares several components. A hook recorded outside any component carries an empty string (the visitor only records hooks inside a component, so this is the rare top-level / unattributed case).
