Struct bytecodec::fixnum::F64beEncoder

pub struct F64beEncoder(_);

Encoder which encodes f64 values by big-endian byte order.

Examples

use bytecodec::EncodeExt;
use bytecodec::fixnum::F64beEncoder;
use bytecodec::io::IoEncodeExt;

let mut output = Vec::new();
let mut encoder = F64beEncoder::with_item(123.456).unwrap();
encoder.encode_all(&mut output).unwrap();
assert_eq!(output, [64, 94, 221, 47, 26, 159, 190, 119]);

Methods

impl F64beEncoder

pub fn new() -> Self

Makes a new F64beEncoder instance.

Trait Implementations

impl Debug for F64beEncoder

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

Formats the value using the given formatter.

impl Default for F64beEncoder

fn default() -> F64beEncoder

Returns the "default value" for a type.

impl Encode for F64beEncoder

type Item = f64

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.

fn cancel(&mut self) -> Result<()>

Cancels the current encoding and makes the encoder's state idle.

impl ExactBytesEncode for F64beEncoder

fn exact_requiring_bytes(&self) -> u64

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