BorrowedShreddingState

Struct BorrowedShreddingState 

pub struct BorrowedShreddingState<'a> {
    value: Option<&'a GenericByteViewArray<BinaryViewType>>,
    typed_value: Option<&'a Arc<dyn Array>>,
}
Expand description

Similar to ShreddingState except it holds borrowed references of the target arrays. Useful for avoiding clone operations when the caller does not need a self-standing shredding state.

Implementations§

§

impl<'a> BorrowedShreddingState<'a>

pub fn new( value: Option<&'a GenericByteViewArray<BinaryViewType>>, typed_value: Option<&'a Arc<dyn Array>>, ) -> BorrowedShreddingState<'a>

Create a new BorrowedShreddingState from the given value and typed_value fields

Note you can create a BorrowedShreddingState from a &[StructArray] using BorrowedShreddingState::try_from(&struct_array), for example:

let struct_array: StructArray = get_struct_array();
let shredding_state = BorrowedShreddingState::try_from(&struct_array).unwrap();

pub fn value_field(&self) -> Option<&'a GenericByteViewArray<BinaryViewType>>

Return a reference to the value field, if present

pub fn typed_value_field(&self) -> Option<&'a Arc<dyn Array>>

Return a reference to the typed_value field, if present
