Struct ReactHookProfile 

pub struct ReactHookProfile {
    pub state: u16,
    pub effect: u16,
    pub memo: u16,
    pub callback: u16,
    pub custom: u16,
    pub max_effect_dep_arity: Option<u32>,
}

Per-component React hook profile derived from the cached hook_uses IR at the health layer. Descriptive context that refines the bare ComplexityViolation::react_hook_count headline with a per-kind breakdown and the maximum useEffect dependency-array arity.

Attached only when at least one component-scope hook was attributed to the function, so non-React findings stay byte-identical on the wire. The per-kind counts cover hooks recorded by the React visitor (calls inside an identified component); a use* call inside a plain helper function is counted in react_hook_count but NOT here, so the breakdown can sum to LESS than react_hook_count. react_hook_count remains the headline total; this is an additive refinement.

Fields

state: u16

useState call count attributed to this component.

effect: u16

useEffect call count attributed to this component.

memo: u16

useMemo call count attributed to this component.

callback: u16

useCallback call count attributed to this component.

custom: u16

Custom use* hook call count attributed to this component.

max_effect_dep_arity: Option<u32>

Largest useEffect dependency-array arity over the attributed effects that carry a literal deps array. None when no attributed useEffect had a literal array (absent or non-literal deps; ADR-001 syntactic-only, so absence does NOT mean “no coupling”).

Implementations

impl ReactHookProfile

pub fn total(&self) -> u16

Total component-scope hooks attributed (state + effect + memo + callback

• custom). Used to gate whether the profile is surfaced at all.

pub fn is_empty(&self) -> bool

true when no hook was attributed, so the profile carries no signal.
