Builder for ArrayData type

Implementations

impl ArrayDataBuilder

pub const fn new(data_type: DataType) -> Self

pub fn data_type(self, data_type: DataType) -> Self

pub const fn len(self, n: usize) -> Self

pub fn null_count(self, null_count: usize) -> Self

pub fn null_bit_buffer(self, buf: Option<Buffer>) -> Self

pub const fn offset(self, n: usize) -> Self

pub fn buffers(self, v: Vec<Buffer>) -> Self

pub fn add_buffer(self, b: Buffer) -> Self

pub fn child_data(self, v: Vec<ArrayData>) -> Self

pub fn add_child_data(self, r: ArrayData) -> Self

pub unsafe fn build_unchecked(self) -> ArrayData

Creates an array data, without any validation

Safety

The same caveats as ArrayData::new_unchecked apply.

pub fn build(self) -> Result<ArrayData, ArrowError>

Creates an array data, validating all inputs
