Struct UseRwLockMutation 

pub struct UseRwLockMutation {
    pub target_struct: Option<String>,
}

Suggests replacing Mutex with RwLock for read-heavy access patterns.

Detection: Mutex fields with collections (HashMap, Vec, etc.) that are typically read more often than written.

Example

// Before
struct Cache {
    data: Mutex<HashMap<String, Value>>,
}

// After (suggested)
struct Cache {
    data: RwLock<HashMap<String, Value>>,
}

Fields

target_struct: Option<String>

Only apply to specific struct
