Struct HookContextInner 

pub struct HookContextInner {
    pub hooks: Vec<Box<dyn Any>>,
    pub arm_changed: usize,
    pub hook_index: usize,
    pub cleanups: Vec<Box<dyn FnOnce()>>,
}

Internal storage for hook state, holding boxed Any values.

This struct is not exposed directly; use HookContext instead. The arm_changed flag tracks whether a match arm switch occurred; when toggled, the hook array is cleared to prevent signal leakage between different match arms.

Fields

hooks: Vec<Box<dyn Any>>

Storage for hook state values (signals, etc.).

arm_changed: usize

The match arm index from the last render.

hook_index: usize

Current hook index, incremented on each hook call and reset per render.

cleanups: Vec<Box<dyn FnOnce()>>

Cleanup closures registered by hooks (e.g., use_signal) that must be executed when the hook context is cleared due to a match arm switch.
