Crate boa_engine
source · [−]Expand description
This is an experimental Javascript lexer, parser and compiler written in Rust. Currently, it has support for some of the language.
Crate Features
- serde - Enables serialization and deserialization of the AST (Abstract Syntax Tree).
- console - Enables
boa’s WHATWGconsoleobject implementation. - profiler - Enables profiling with measureme (this is mostly internal).
- intl - Enables
boa’s ECMA-402 Internationalization API (Intlobject)
Modules
This module implements the JavaScript bigint primitive rust type.
Builtins live here, such as Object, String, Math, etc.
Traits and structs for implementing native classes.
Javascript context.
This module implements ECMAScript Environment Records.
This module implements the Rust representation of a JavaScript object.
A convenience module that re-exports the most commonly-used Boa APIs
This module implements the Property Descriptor.
Conceptually, a realm consists of a set of intrinsic objects, an ECMAScript global environment, all of the ECMAScript code that is loaded within the scope of that global environment, and other associated state and resources.
This module implements the global Symbol object.
Syntactical analysis, such as Abstract Syntax Tree (AST), Parsing and Lexing
This module implements the JavaScript Value.
The Virtual Machine (VM) handles generating instructions, then executing them. This module will provide an instruction set for the AST to use, various traits, plus an interpreter to execute those instructions
Structs
Javascript context. It is the primary way to interact with the runtime.
JavaScript bigint primitive rust type.
This represents a JavaScript primitive string.
This represents a JavaScript symbol primitive.
Enums
A Javascript value
Type Definitions
The result of a Javascript expression is represented like this so it can succeed (Ok) or fail (Err)
