impl Int32Array
pub fn fill(&self, value: i32, start: u32, end: u32) -> Int32Array
[src]
pub fn fill(&self, value: i32, start: u32, end: u32) -> Int32Array
The fill() method fills all the elements of an array from a start index to an end index with a static value. The end index is not included.
impl Int32Array
[src]
impl Int32Array
pub fn buffer(&self) -> ArrayBuffer
[src]
pub fn buffer(&self) -> ArrayBuffer
The buffer
accessor property represents the ArrayBuffer
referenced
by a TypedArray
at construction time.
impl Int32Array
[src]
impl Int32Array
pub fn subarray(&self, begin: u32, end: u32) -> Int32Array
[src]
pub fn subarray(&self, begin: u32, end: u32) -> Int32Array

method stores multiple values in the typed array,
reading input values from a specified array.
impl Int32Array
[src]
impl Int32Array
pub fn slice(&self, begin: u32, end: u32) -> Int32Array
[src]
pub fn slice(&self, begin: u32, end: u32) -> Int32Array
The slice()
method returns a shallow copy of a portion of a typed
array into a new typed array object. This method has the same algorithm
as Array.prototype.slice()
.
impl Int32Array
[src]
impl Int32Array
pub fn for_each(&self, callback: &mut dyn FnMut(i32, u32, Int32Array))
[src]
pub fn for_each(&self, callback: &mut dyn FnMut(i32, u32, Int32Array))
The forEach()
method executes a provided function once per array
element. This method has the same algorithm as
Array.prototype.forEach()
. TypedArray
is one of the typed array
types here.
impl Int32Array
[src]
impl Int32Array
pub fn length(&self) -> u32
[src]
pub fn length(&self) -> u32
The length
accessor property represents the length (in elements) of a
typed array.
impl Int32Array
[src]
impl Int32Array
pub fn byte_length(&self) -> u32
[src]
pub fn byte_length(&self) -> u32
The byteLength
accessor property represents the length (in bytes) of a
typed array.
impl Int32Array
[src]
impl Int32Array
pub fn byte_offset(&self) -> u32
[src]
pub fn byte_offset(&self) -> u32
The byteOffset
accessor property represents the offset (in bytes) of a
typed array from the start of its ArrayBuffer
.
impl Int32Array
[src]
impl Int32Array
pub fn set(&self, src: &JsValue, offset: u32)
[src]
pub fn set(&self, src: &JsValue, offset: u32)
The set()
method stores multiple values in the typed array, reading
input values from a specified array.
impl Int32Array
[src]
impl Int32Array
pub unsafe fn view(rust: &[i32]) -> Int32Array
[src]
pub unsafe fn view(rust: &[i32]) -> Int32Array
Creates a JS typed array which is a view into wasm's linear memory at the slice specified.
This function returns a new typed array which is a view into wasm's memory. This view does not copy the underlying data.
Unsafety
Views into WebAssembly memory are only valid so long as the
backing buffer isn't resized in JS. Once this function is called
any future calls to Box::new
(or malloc of any form) may cause
the returned value here to be invalidated. Use with caution!
Additionally the returned object can be safely mutated but the input slice isn't guaranteed to be mutable.
Finally, the returned object is disconnected from the input slice's lifetime, so there's no guarantee that the data is read at the right time.
pub fn copy_to(&self, dst: &mut [i32])
[src]
pub fn copy_to(&self, dst: &mut [i32])
Copy the contents of this JS typed array into the destination Rust slice.
This function will efficiently copy the memory from a typed array into this wasm module's own linear memory, initializing the memory destination provided.
Panics
This function will panic if this typed array's length is
different than the length of the provided dst
array.
Methods from Deref<Target = Object>
pub fn has_own_property(&self, property: &JsValue) -> bool
[src]
pub fn has_own_property(&self, property: &JsValue) -> bool
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
pub fn is_prototype_of(&self, value: &JsValue) -> bool
[src]
pub fn is_prototype_of(&self, value: &JsValue) -> bool
The isPrototypeOf()
method checks if an object exists in another
object's prototype chain.
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
[src]
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
pub fn to_locale_string(&self) -> JsString
[src]
pub fn to_locale_string(&self) -> JsString
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
pub fn to_string(&self) -> JsString
[src]
pub fn to_string(&self) -> JsString
The toString()
method returns a string representing the object.
pub fn value_of(&self) -> Object
[src]
pub fn value_of(&self) -> Object
The valueOf()
method returns the primitive value of the
specified object.
