Struct StructVector 

pub struct StructVector<'a> { /* private fields */ }

A struct vector borrowed from a DataChunkHandle.

Groups one child vector per struct field, all sharing the same row count.

Implementations

impl<'a> StructVector<'a>

pub fn child(&self, idx: usize, capacity: usize) -> FlatVector<'a>

Returns the child by idx in the struct vector.

Panics

Panics if capacity exceeds the parent vector capacity.

pub fn struct_vector_child(&self, idx: usize) -> StructVector<'a>

Take the child as StructVector.

pub fn list_vector_child(&self, idx: usize) -> ListVector<'a>

Take the child as ListVector.

pub fn array_vector_child(&self, idx: usize) -> ArrayVector<'a>

Take the child as ArrayVector.

pub fn logical_type(&self) -> LogicalTypeHandle

Get the logical type of this struct vector.

pub fn row_is_null(&self, row: u64) -> bool

Returns true if the row at the given index is null.

Panics

Panics if row is outside the vector capacity.

pub fn try_row_is_null(&self, row: u64) -> Result<bool>

Returns whether the row is null, or an error if it is out of range.

pub fn child_name(&self, idx: usize) -> DuckDbString

Get the name of the child by idx.

Panics if idx is out of range.

pub fn num_children(&self) -> usize

Get the number of children.

pub fn set_null(&mut self, row: usize)

Set row as null
