Struct ImageData

pub struct ImageData(/* private fields */);

The ImageData struct represents the underlying pixel data of an area of a <canvas> element. You can create a new instance by calling CanvasRenderingContext2d::create_image_data or CanvasRenderingContext2d::create_image_data_size_of.

Trait Implementations

impl AsRef<Reference> for ImageData

fn as_ref(&self) -> &Reference

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ImageData

fn clone(&self) -> ImageData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageData

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

Formats the value using the given formatter.

impl From<ImageData> for Reference

fn from(value: ImageData) -> Self

Converts to this type from the input type.

impl InstanceOf for ImageData

fn instance_of(reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.

impl ReferenceType for ImageData

unsafe fn from_reference_unchecked(reference: Reference) -> Self

Converts a given reference into a concrete reference-like wrapper. Doesn’t do any type checking; highly unsafe to use!

impl<'_r> TryFrom<&'_r Reference> for ImageData

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(reference: &Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl<'_r> TryFrom<&'_r Value> for ImageData

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<ImageData> for Reference

type Error = Void

The type returned in the event of a conversion error.

fn try_from(value: ImageData) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Reference> for ImageData

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(reference: Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for ImageData

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl JsSerialize for ImageData
