Struct BorrowedShreddingState 

pub struct BorrowedShreddingState<'a> {
    value: Option<&'a BinaryViewArray>,
    typed_value: Option<&'a ArrayRef>,
}

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.

Fields

value: Option<&'a BinaryViewArray>

typed_value: Option<&'a ArrayRef>

Implementations

impl<'a> BorrowedShreddingState<'a>

pub fn new( value: Option<&'a BinaryViewArray>, typed_value: Option<&'a ArrayRef>, ) -> Self

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 BinaryViewArray>

Return a reference to the value field, if present

pub fn typed_value_field(&self) -> Option<&'a ArrayRef>

Return a reference to the typed_value field, if present
