Skip to main content Crate sfo_js Copy item path Source ast Boa’s boa_ast bigint Boa’s implementation of ECMAScript’s bigint primitive type. builtins Boa’s ECMAScript built-in object implementations, e.g. Object, String, Math, Array, etc. bytecompiler This module contains the bytecode compiler. class Traits and structs for implementing native classes. clone Module containing all types and functions to implement structuredClone. console Boa’s implementation of JavaScript’s console Web API object. context The ECMAScript context. environments Boa’s implementation of ECMAScript’s Environment Records. error Error-related types and conversions. extensions This module contains all the Runtime extensions that can be registered. fetch Boa’s implementation of JavaScript’s fetch function. gc Boa’s boa_gc interner Boa’s boa_interner interop Interop module containing traits and types to ease integration between Boa
and Rust. interval A module that declares any functions for dealing with intervals or
timeouts. job Boa’s API to create and customize ECMAScript jobs and job queues. message Boa’s implementation of the Message API (mainly postMessage and
supporting functions). microtask Microtask-related functions and types. module Boa’s implementation of the ECMAScript’s module system. native_function Boa’s wrappers for native Rust functions to be compatible with ECMAScript calls. object Boa’s representation of a JavaScript object and builtin object wrappers optimizer Implements optimizations. parser Boa’s boa_parserECMAScript language specification . prelude A convenience module that re-exports the most commonly-used Boa APIs property Boa’s implementation of ECMAScript’s Property Descriptor. realm Boa’s implementation of ECMAScript’s Realm Records script Boa’s implementation of ECMAScript’s Scripts. store Module containing the types related to the JsValueStore string This module contains the js_stringjs_str symbol Boa’s implementation of ECMAScript’s global Symbol object. text Module implementing JavaScript classes to handle text encoding and decoding. url Boa’s implementation of JavaScript’s URL Web API class. value Boa’s ECMAScript Value implementation. vm Boa’s ECMAScript Virtual Machine __embed_module_inner Implementation of the inner iterator of the embed_module! macro. All
arguments are required. embed_module Create a module loader that embeds files from the filesystem at build
time. This is useful for bundling assets with the binary. embed_module_inner Implementation of the inner iterator of the embed_module! macro. All
arguments are required. into_js_pkg_err js_error Create an error object from a value or string literal. Optionally the
first argument of the macro can be a type of error (such as TypeError,
RangeError or InternalError). js_object Create a JsObject object from a simpler DSL that resembles JSON. js_pkg_err js_str Convert a utf8 string literal to a JsString js_string Utility macro to create a JsString js_value The js_value! macro creates a JsValue instance based on a JSON-like DSL. utf16 Construct a utf-16 array literal from a utf-8 str Console This is the internal console object state. ConsoleState The current state of the console, passed to the logger backend.
This should not be copied or cloned. References are only valid
for the current logging call. Context ECMAScript context. It is the primary way to interact with the runtime. DefaultLogger The default implementation for logging from the console. HostDefined This represents a ECMASCript specification [HostDefined] field. JsBigInt JavaScript bigint primitive rust type. JsEngine JsEngineBuilder JsError The error type returned by all operations related
to the execution of Javascript code. JsNativeError Native representation of an ideal Error object from Javascript. JsObject Garbage collected Object. JsPkg JsPkgConfig JsPkgManager JsStr This is equivalent to Rust’s &str. JsString A Latin1 or UTF-16–encoded, reference counted, immutable string. JsSymbol This represents a JavaScript symbol primitive. JsValue A generic JavaScript value. This can be any ECMAScript language valid value. Module ECMAScript’s Abstract module record NativeFunction A callable Rust function that can be invoked by the engine. NullLogger A logger that drops all logging. Useful for testing. Script ECMAScript’s Script Record Source A source of ECMAScript code. SpannedSourceText Contains pointer to source code and span of the object. JsNativeErrorKind The list of possible error types a JsNativeError JsVariant A non-mutable variant of a JsValue.
Represents either a primitive value (boolf64i32JsStringJsSymbol Finalize Substitute for the Drop IntoJsFunctionCopied The safe equivalent of the UnsafeIntoJsFunctionCopy trait. IntoJsModule A trait to convert a type into a JS module. JsArgs A utility trait to make working with function arguments easier. JsData Represents a type that can be stored inside a JsObject. Logger A trait that can be used to forward console logs to an implementation. NativeObject This trait allows Rust types to be passed around as objects. RuntimeExtension Optional registrable extension (with arguments) in the Boa Runtime should
implement this. Trace The Trace trait, which needs to be implemented on garbage-collected objects. TryIntoJsResult Create a JsResultJsResultJsValue UnsafeIntoJsFunction A trait to convert a type into a JS function.
This trait does not require the implementing type to be Copy, which
can lead to undefined behaviour if it contains Garbage Collected objects. register Register all the built-in objects and functions of the WebAPI runtime, plus
any extensions defined. register_extensions Register only the extensions provided. An application can use this to register
extensions that it previously hadn’t registered. JsEngineInitCallback JsPkgManagerRef JsPkgResult JsResult The result of a Javascript expression is represented like this so it can succeed (Ok) or fail (Err) boa_class boa_class proc macro attribute that applies to an impl XYZ block and
add a [boa_engine::JsClass] implementation for it.boa_module boa_module proc macro attribute for declaring a boa_engine::Module based
on a Rust module. The original Rust module will also be exposed as is.Finalize Derive the Finalize trait. JsData Derive the JsData trait. Trace Derive the Trace trait. TryFromJs Derives the TryFromJs trait, with the #[boa()] attribute. TryIntoJs Derives the TryIntoJs trait, with the #[boa()] attribute.
