Struct parquet::data_type::ByteArray

pub struct ByteArray { /* fields omitted */ }

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

Methods

impl ByteArray

pub fn new() -> Self

Creates new byte array with no data set.

pub fn len(&self) -> usize

Gets length of the underlying byte buffer.

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

Returns slice of data.

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

Set data from another byte buffer.

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

Returns ByteArray instance with slice of values for a data.

Trait Implementations

impl Clone for ByteArray

fn clone(&self) -> ByteArray

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ByteArray

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

Formats the value using the given formatter.

impl From<Vec<u8>> for ByteArray

fn from(buf: Vec<u8>) -> ByteArray

Performs the conversion.

impl<'a> From<&'a str> for ByteArray

fn from(s: &'a str) -> ByteArray

Performs the conversion.

impl From<ByteBufferPtr> for ByteArray

fn from(ptr: ByteBufferPtr) -> ByteArray

Performs the conversion.

impl From<ByteBuffer> for ByteArray

fn from(buf: ByteBuffer) -> ByteArray

Performs the conversion.

impl Default for ByteArray

fn default() -> Self

Returns the "default value" for a type.

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 !=.

impl Rand for ByteArray

fn rand<R: Rng>(rng: &mut R) -> Self

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Generates a random instance of this type using the specified source of randomness.

impl AsBytes for ByteArray

fn as_bytes(&self) -> &[u8]

Returns slice of bytes for this data type.
