Struct UTF32Encoder 

pub struct UTF32Encoder;

A 32-bit encoder for UTF-32.

Examples

use conversion::converter::encoding::utf32::UTF32Encoder;
use conversion::iter::ConvertedIterator;

let iter = "💯❤".chars();
let encoded = ConvertedIterator::new(iter, UTF32Encoder::new());

assert_eq!(Ok(vec![0x1F4AF, 0x2764]), encoded.collect());

Implementations

impl UTF32Encoder

pub fn new() -> Self

Create a new instance.

Trait Implementations

impl Clone for UTF32Encoder

fn clone(&self) -> UTF32Encoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Converter for UTF32Encoder

type Item = char

The type of input items.

type Output = u32

The type of outputs.

type Error = Infallible

The type of errors while conversion.

fn convert<E>( &mut self, item: Self::Item, buf: &mut E, ) -> Result<usize, Self::Error>

where E: Extend<Self::Output>,

Consumes one item, stores outputs into buf implements Extend, and returns the number of stored outputs or a conversion error. If there are no outputs yet, you should store the item and return Ok(0).

fn size_hint(&self) -> (usize, Option<usize>)

Returnd the estimated bounds about the numbers of outputs that one item will produce.

fn is_ended(&self) -> bool

Returns whether the converter reached the end, or not.

fn finalize(&mut self) -> Result<(), Self::Error>

Finalizing the converter.

fn chain<C>(self, other: C) -> ChainedConverter<Self, C>

where C: Converter<Item = Self::Item, Output = Self::Output>, Self: Sized,

Chaining two converters.

impl Debug for UTF32Encoder

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

Formats the value using the given formatter.

impl Default for UTF32Encoder

fn default() -> UTF32Encoder

Returns the “default value” for a type.

impl PartialEq for UTF32Encoder

fn eq(&self, other: &UTF32Encoder) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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