Struct deltalake::datafusion::parquet::data_type::ByteArray

pub struct ByteArray { /* private fields */ }

Rust representation for BYTE_ARRAY and FIXED_LEN_BYTE_ARRAY Parquet physical types. Value is backed by a byte buffer.

Implementations

impl ByteArray

pub fn new() -> ByteArray

Creates new byte array with no data set.

pub fn len(&self) -> usize

Gets length of the underlying byte buffer.

pub fn is_empty(&self) -> bool

Checks if the underlying buffer is empty.

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

Returns slice of data.

pub fn set_data(&mut self, data: Bytes)

Set data from another byte buffer.

pub fn slice(&self, start: usize, len: usize) -> ByteArray

Returns ByteArray instance with slice of values for a data.

pub fn as_utf8(&self) -> Result<&str, ParquetError>

impl PartialEq for ByteArray

fn eq(&self, other: &ByteArray) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
