Struct LargeBinary 

pub struct LargeBinary(/* private fields */);

Wrapper denoting Arrow LargeBinary values. Use when individual binary values can exceed 2GB or when 64-bit offsets are preferred.

Implementations

impl LargeBinary

pub fn new(value: Vec<u8>) -> Self

Construct a new LargeBinary from the given bytes.

pub fn as_slice(&self) -> &[u8]

Return the underlying bytes as a slice.

pub fn into_vec(self) -> Vec<u8>

Consume and return the underlying byte vector.

Trait Implementations

impl ArrowBinding for LargeBinary

type Builder = GenericByteBuilder<GenericBinaryType<i64>>

Concrete Arrow builder type used for this Rust type.

type Array = GenericByteArray<GenericBinaryType<i64>>

Concrete Arrow array type produced by finish.

fn data_type() -> DataType

The Arrow DataType corresponding to this Rust type.

fn new_builder(capacity: usize) -> Self::Builder

Create a new builder with an optional capacity hint.

fn append_value(b: &mut Self::Builder, v: &Self)

Append a non-null value to the builder.

fn append_null(b: &mut Self::Builder)

Append a null to the builder.

fn finish(b: Self::Builder) -> Self::Array

Finish the builder and produce a typed Arrow array.

fn estimated_bytes_per_value() -> usize

Estimated bytes per value for variable-length types (String, Binary, etc.). Returns 0 for fixed-size types. Used to pre-allocate buffer space.

impl ArrowBindingView for LargeBinary

Available on crate feature views only.

type Array = GenericByteArray<GenericBinaryType<i64>>

The Arrow array type this view reads from.

type View<'a> = &'a [u8]

The borrowed view type returned when accessing array elements. For example: &'a str for StringArray, i64 for Int64Array.

fn get_view( array: &Self::Array, index: usize, ) -> Result<Self::View<'_>, ViewAccessError>

Extract a view at the given index from the array.

impl From<Vec<u8>> for LargeBinary

fn from(value: Vec<u8>) -> Self

Converts to this type from the input type.
