# Objective
- Make the function signature for `ComponentHook` less verbose
## Solution
- Refactored `Entity`, `ComponentId`, and `Option<&Location>` into a new
`HookContext` struct.
## Testing
- CI
---
## Migration Guide
Update the function signatures for your component hooks to only take 2
arguments, `world` and `context`. Note that because `HookContext` is
plain data with all members public, you can use de-structuring to
simplify migration.
```rust
// Before
fn my_hook(
mut world: DeferredWorld,
entity: Entity,
component_id: ComponentId,
) { ... }
// After
fn my_hook(
mut world: DeferredWorld,
HookContext { entity, component_id, caller }: HookContext,
) { ... }
```
Likewise, if you were discarding certain parameters, you can use `..` in
the de-structuring:
```rust
// Before
fn my_hook(
mut world: DeferredWorld,
entity: Entity,
_: ComponentId,
) { ... }
// After
fn my_hook(
mut world: DeferredWorld,
HookContext { entity, .. }: HookContext,
) { ... }
```
