Struct ListStorage 

pub struct ListStorage<T>
where
    T: Clone,
{ /* private fields */ }

Generic storage for Vec fields

Supports two modes:

• Owned: Python-created Vec, stored in Box
• Borrowed: Reference to Vec field in a component

Implementations

impl<T> ListStorage<T>

where T: Clone,

pub fn owned(vec: Vec<T>) -> ListStorage<T>

Create owned list storage

pub unsafe fn borrowed( ptr: *mut Vec<T>, validity: ValidityFlagWithMode, ) -> ListStorage<T>

Create borrowed list storage with direct pointer to Vec

Safety

• ptr must point to a valid Vec<T> in a component field
• The pointer must remain valid while validity flag is true

pub fn as_ref(&self) -> Result<&Vec<T>, StorageError>

Get immutable reference to the Vec, checking validity

pub fn as_mut(&mut self) -> Result<&mut Vec<T>, StorageError>

Get mutable reference to the Vec, checking validity and write permission

pub fn get(&self) -> Result<Vec<T>, StorageError>

Get a clone of the Vec

pub fn len(&self) -> Result<usize, StorageError>

Get length of the Vec

pub fn is_empty(&self) -> Result<bool, StorageError>

Check if Vec is empty
