Enum TextDecoder 

pub enum TextDecoder {
    Utf8,
    Utf16Le,
    Utf16Be,
}

The TextDecoder class represents an encoder for a specific method, that is a specific character encoding, like utf-8.

Variants

Utf8

Decode bytes encoded as UTF-8 into strings.

Utf16Le

Decode bytes encoded as UTF-16 (little endian) into strings.

Utf16Be

Decode bytes encoded as UTF-16 (big endian) into strings.

Implementations

impl TextDecoder

pub fn constructor( encoding: Option<JsString>, _options: Option<JsObject>, ) -> Result<TextDecoder, JsError>

The TextDecoder() constructor returns a new TextDecoder object.

Errors

This will return an error if the encoding or options are invalid or unsupported.

pub fn encoding(&self) -> JsString

The TextDecoder.encoding read-only property returns a string containing the name of the character encoding that this decoder will use.

pub fn decode( &self, buffer: JsValue, context: &mut Context, ) -> Result<JsString, JsError>

The TextDecoder.decode() method returns a string containing text decoded from the buffer passed as a parameter.

Errors

Any error that arises during decoding the specific encoding.

Trait Implementations

impl Class for TextDecoder

const NAME: &'static str = "TextDecoder"

The binding name of this class.

const LENGTH: usize = 2usize

The amount of arguments this class’ constructor takes. Default is 0.

fn data_constructor( this: &JsValue, args: &[JsValue], context: &mut Context, ) -> Result<TextDecoder, JsError>

Creates the internal data for an instance of this class.

fn init(builder: &mut ClassBuilder<'_>) -> Result<(), JsError>

Initializes the properties and methods of this class.

const ATTRIBUTES: Attribute = _

The property attributes of this class’ constructor in the global object. Default is writable, enumerable, configurable.

fn object_constructor( instance: &JsObject, args: &[JsValue], context: &mut Context, ) -> Result<(), JsError>

Initializes the properties of the constructed object for an instance of this class.

fn construct( new_target: &JsValue, args: &[JsValue], context: &mut Context, ) -> Result<JsObject, JsError>

Creates a new JsObject with its internal data set to the result of calling Class::data_constructor and Class::object_constructor.

fn from_data(data: Self, context: &mut Context) -> Result<JsObject, JsError>

Constructs an instance of this class from its inner native data.

impl Clone for TextDecoder

fn clone(&self) -> TextDecoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextDecoder

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

Formats the value using the given formatter.

impl Default for TextDecoder

fn default() -> TextDecoder

Returns the “default value” for a type.

impl Drop for TextDecoder

fn drop(&mut self)

Executes the destructor for this type.

impl Finalize for TextDecoder

fn finalize(&self)

Cleanup logic for a type.

impl Trace for TextDecoder

unsafe fn trace(&self, tracer: &mut Tracer)

Marks all contained Gcs.

unsafe fn trace_non_roots(&self)

Trace handles located in GC heap, and mark them as non root.

fn run_finalizer(&self)

Runs Finalize::finalize on this object and all contained subobjects.
