Struct bytecodec::fixnum::U40beEncoder

pub struct U40beEncoder(_);

Encoder which encodes unsigned 40-bit integers by big-endian byte order.

Although the type of items is u64, the most significant 24-bits must be 0.

Examples

use bytecodec::EncodeExt;
use bytecodec::fixnum::U40beEncoder;
use bytecodec::io::IoEncodeExt;

let mut output = Vec::new();
let mut encoder = U40beEncoder::with_item(0x0000_0001_0203_0405).unwrap();
encoder.encode_all(&mut output).unwrap();
assert_eq!(output, [0x01, 0x02, 0x03, 0x04, 0x05]);

Methods

impl U40beEncoder

pub fn new() -> Self

Makes a new U40beEncoder instance.

Trait Implementations

impl Debug for U40beEncoder

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for U40beEncoder

fn default() -> U40beEncoder

Returns the "default value" for a type.

impl Encode for U40beEncoder

type Item = u64

The type of items to be encoded.

fn encode(&mut self, buf: &mut [u8], eos: Eos) -> Result<usize>

Encodes the items in the encoder and writes the encoded bytes to the given buffer.

fn start_encoding(&mut self, item: Self::Item) -> Result<()>

Tries to start encoding the given item.

fn requiring_bytes(&self) -> ByteCount

Returns the number of bytes required to encode all the items in the encoder.

fn is_idle(&self) -> bool

Returns true if there are no items to be encoded in the encoder, otherwise false.

impl ExactBytesEncode for U40beEncoder

fn exact_requiring_bytes(&self) -> u64

Returns the exact number of bytes required to encode all the items remaining in the encoder.
