Struct arrow::ffi::ArrowArrayChild

pub struct ArrowArrayChild<'a> { /* fields omitted */ }

Trait Implementations

impl<'a> ArrowArrayRef for ArrowArrayChild<'a>

fn data_type(&self) -> Result<DataType>

the data_type as declared in the schema

fn array(&self) -> &FFI_ArrowArray

fn schema(&self) -> &FFI_ArrowSchema

fn owner(&self) -> &Arc<FFI_ArrowArray>

fn to_data(&self) -> Result<ArrayData>

fn buffers(&self) -> Result<Vec<Buffer>>

returns all buffers, as organized by Rust (i.e. null buffer is skipped)

fn buffer_len(&self, i: usize) -> Result<usize>

Returns the length, in bytes, of the buffer i (indexed according to the C data interface)

fn null_bit_buffer(&self) -> Option<Buffer>

returns the null bit buffer. Rust implementation uses a buffer that is not part of the array of buffers. The C Data interface’s null buffer is part of the array of buffers.

fn child(&self, index: usize) -> ArrowArrayChild<'_>

impl<'a> Debug for ArrowArrayChild<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
