Module builtins 

All Rust API wrappers for Boa’s ECMAScript objects.

The structs available in this module provide functionality to interact with native ECMAScript objects from Rust.

Structs

JsArray

JsArray provides a wrapper for Boa’s implementation of the JavaScript Array object.

JsArrayBuffer

JsArrayBuffer provides a wrapper for Boa’s implementation of the ECMAScript ArrayBuffer object

JsAsyncGenerator

JsAsyncGenerator provides a wrapper for Boa’s implementation of the ECMAScript AsyncGenerator builtin object.

JsBigInt64Array

JsBigInt64Array provides a wrapper for Boa’s implementation of the ECMAScript BigInt64Array builtin object.

JsBigUint64Array

JsBigUint64Array provides a wrapper for Boa’s implementation of the ECMAScript BigUint64Array builtin object.

JsDataView

JsDataView provides a wrapper for Boa’s implementation of the ECMAScript DataView object

JsDate

JsDate is a wrapper for JavaScript JsDate builtin object

JsFloat16Array

JsFloat16Array provides a wrapper for Boa’s implementation of the ECMAScript Float16Array builtin object.

JsFloat32Array

JsFloat32Array provides a wrapper for Boa’s implementation of the ECMAScript Float32Array builtin object.

JsFloat64Array

JsFloat64Array provides a wrapper for Boa’s implementation of the ECMAScript Float64Array builtin object.

JsFunction

JavaScript Function rust object.

JsFuture

A Rust’s Future that becomes ready when a JsPromise fulfills.

JsGenerator

JsGenerator provides a wrapper for Boa’s implementation of the ECMAScript Generator builtin object

JsGeneratorFunction

JsGeneratorFunction provides a wrapper for Boa’s implementation of the ECMAScript GeneratorFunction builtin object.

JsInt8Array

JsInt8Array provides a wrapper for Boa’s implementation of the ECMAScript Int8Array builtin object.

JsInt16Array

JsInt16Array provides a wrapper for Boa’s implementation of the ECMAScript Int16Array builtin object.

JsInt32Array

JsInt32Array provides a wrapper for Boa’s implementation of the ECMAScript Int32Array builtin object.

JsMap

JsMap provides a wrapper for Boa’s implementation of the ECMAScript Map object.

JsMapIterator

JsMapIterator provides a wrapper for Boa’s implementation of the ECMAScript MapIterator object.

JsPromise

An ECMAScript promise object.

JsProxy

JsProxy provides a wrapper for Boa’s implementation of the ECMAScript Proxy object

JsProxyBuilder

Utility builder to create JsProxy objects from native functions.

JsRegExp

JsRegExp provides a wrapper for Boa’s implementation of the ECMAScript RegExp builtin object

JsRevocableProxy

JsRevocableProxy provides a wrapper for JsProxy that can be disabled.

JsSet

JsSet provides a wrapper for Boa’s implementation of the ECMAScript Set object.

JsSetIterator

JsSetIterator provides a wrapper for Boa’s implementation of the ECMAScript SetIterator object

JsSharedArrayBuffer

JsSharedArrayBuffer provides a wrapper for Boa’s implementation of the ECMAScript ArrayBuffer object

JsTypedArray

JsTypedArray provides a wrapper for Boa’s implementation of the ECMAScript TypedArray builtin object.

JsUint8Array

JsUint8Array provides a wrapper for Boa’s implementation of the ECMAScript Uint8Array builtin object.

JsUint8ClampedArray

JsUint8ClampedArray provides a wrapper for Boa’s implementation of the ECMAScript Uint8ClampedArray builtin object.

JsUint16Array

JsUint16Array provides a wrapper for Boa’s implementation of the ECMAScript Uint16Array builtin object.

JsUint32Array

JsUint32Array provides a wrapper for Boa’s implementation of the ECMAScript Uint32Array builtin object.

JsWeakMap

JsWeakMap provides a wrapper for Boa’s implementation of the ECMAScript WeakMap object.

JsWeakSet

JsWeakSet provides a wrapper for Boa’s implementation of the ECMAScript WeakSet object.

TypedJsFunction

A JavaScript Function rust object, typed. This adds types to a JavaScript exported function, allowing for type checking and type conversion in Rust. Those types must convert to a JsValue but will not be verified at runtime (since JavaScript doesn’t actually have strong typing).

Traits

TryIntoJsArguments

A trait for converting a tuple of Rust values into a vector of JsValue, to be used as arguments for a JavaScript function.

Functions

js_typed_array_from_kind

Create a JsTypedArray from a TypedArrayKind and a backing JsArrayBuffer.

Type Aliases

AlignedVec

Vec, but aligned to a 64-bit memory address.
