Struct GetContextCallback 

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

Wrapper around CallbackWithContext to provide a default implementation

Implementations

impl GetContextCallback

pub fn new(callback: impl Into<GetContextCallback>) -> Self

Methods from Deref<Target = GetContextCallbackInner>

pub fn js(&self) -> Option<CallbackWithContext<J>>

pub fn rs(&self) -> Option<CallbackWithContext<R>>

pub fn js_unwrap(&self) -> CallbackWithContext<J>

pub fn rs_unwrap(&self) -> CallbackWithContext<R>

pub fn js_inner_owned(&self) -> Option<J>

pub fn rs_inner_owned(&self) -> Option<R>

pub fn call_with_no_arg(&self)

If the function is a rust callback, the argument is supplied, otherwise the javascript function is called without any arguments.

pub fn call_with_rust_arg(&self, a: A)

If the function is a rust callback, the argument is supplied, otherwise the javascript function is called without any arguments.

pub fn call_with_rust_arg_and_return(&self, a: A) -> R

If the function is a rust callback, the argument is supplied, otherwise the javascript function is called without any arguments.

Returns the result value

pub fn call_with_js_arg(&self, a: A)

Calls either underlying callback with the argument supplied

pub fn call_with_into_js_arg(&self, a: A)

Calls either underlying callback with the argument supplied

pub fn call_with_as_js_arg(&self, a: A)

Calls either underlying callback with the argument supplied

pub fn call_with_into_js_arg_and_return(&self, a: A) -> R

Calls either underlying callback with the argument supplied and returns the resulting value

Trait Implementations

impl Clone for GetContextCallback

fn clone(&self) -> GetContextCallback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GetContextCallback

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

Formats the value using the given formatter.

impl Default for GetContextCallback

fn default() -> Self

Returns the “default value” for a type.

impl Deref for GetContextCallback

type Target = Callback<dyn Fn(HtmlCanvasElement) -> Result<WebGl2RenderingContext, WebGlContextError>, Function>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<F: Fn(HtmlCanvasElement) -> Result<WebGl2RenderingContext, WebGlContextError> + 'static> From<F> for GetContextCallback

fn from(callback: F) -> Self

Converts to this type from the input type.

impl From<Function> for GetContextCallback

fn from(callback: Function) -> Self

Converts to this type from the input type.

impl<F: Fn(HtmlCanvasElement) -> Result<WebGl2RenderingContext, WebGlContextError> + 'static> From<Rc<F>> for GetContextCallback

fn from(callback: Rc<F>) -> Self

Converts to this type from the input type.

impl Hash for GetContextCallback

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for GetContextCallback

fn eq(&self, other: &GetContextCallback) -> 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.

impl PartialOrd for GetContextCallback

fn partial_cmp(&self, other: &GetContextCallback) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
