Methods

impl Float64Array
[src]

The Float64Array() constructor creates an array of unsigned 8-bit integers.

MDN documentation

impl Float64Array
[src]

An Float64Array() which creates an array with an internal buffer large enough for length elements.

MDN documentation

impl Float64Array
[src]

An Float64Array() which creates an array with the given buffer but is a view starting at byte_offset.

MDN documentation

impl Float64Array
[src]

An Float64Array() which creates an array with the given buffer but is a view starting at byte_offset for length elements.

MDN documentation

impl Float64Array
[src]

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.

MDN documentation

impl Float64Array
[src]

The buffer accessor property represents the ArrayBuffer referenced by a TypedArray at construction time.

impl Float64Array
[src]

The subarray() method stores multiple values in the typed array, reading input values from a specified array.

impl Float64Array
[src]

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 Float64Array
[src]

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 Float64Array
[src]

The length accessor property represents the length (in elements) of a typed array.

impl Float64Array
[src]

The byteLength accessor property represents the length (in bytes) of a typed array.

impl Float64Array
[src]

The byteOffset accessor property represents the offset (in bytes) of a typed array from the start of its ArrayBuffer.

impl Float64Array
[src]

The set() method stores multiple values in the typed array, reading input values from a specified array.

impl Float64Array
[src]

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.

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>

The hasOwnProperty() method returns a boolean indicating whether the object has the specified property as its own property (as opposed to inheriting it).

MDN documentation

The isPrototypeOf() method checks if an object exists in another object's prototype chain.

MDN documentation

The propertyIsEnumerable() method returns a Boolean indicating whether the specified property is enumerable.

MDN documentation

The toLocaleString() method returns a string representing the object. This method is meant to be overridden by derived objects for locale-specific purposes.

MDN documentation

The toString() method returns a string representing the object.

MDN documentation

The valueOf() method returns the primitive value of the specified object.
