Struct Config 

pub struct Config { /* private fields */ }

A configuration for the Javy plugin API.

Implementations

impl Config

pub fn event_loop(&mut self, enabled: bool) -> &mut Self

Whether to enable the event loop.

Methods from Deref<Target = Config>

pub fn date(&mut self, enable: bool) -> &mut Config

Configures whether the JavaScript Date intrinsic will be available.

pub fn eval(&mut self, enable: bool) -> &mut Config

Configures whether the Eval intrinsic will be available.

pub fn regexp_compiler(&mut self, enable: bool) -> &mut Config

Configures whether the regular expression compiler will be available.

pub fn regexp(&mut self, enable: bool) -> &mut Config

Configures whether the RegExp intrinsic will be available.

pub fn json(&mut self, enable: bool) -> &mut Config

Configures whether the QuickJS native JSON intrinsic will be available.

pub fn proxy(&mut self, enable: bool) -> &mut Config

Configures whether proxy object creation will be available. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Proxy

pub fn map_set(&mut self, enable: bool) -> &mut Config

Configures whether the MapSet intrinsic will be available.

pub fn promise(&mut self, enable: bool) -> &mut Config

Configures whether the Promise instrinsic will be available.

pub fn big_int(&mut self, enable: bool) -> &mut Config

Configures whether supoort for BigInt will be available.

pub fn operator_overloading(&mut self, enable: bool) -> &mut Config

Configures whether operator overloading wil be supported.

pub fn bignum_extension(&mut self, enable: bool) -> &mut Config

Configures whether extensions to BigNum will be available.

pub fn text_encoding(&mut self, enable: bool) -> &mut Config

Configures whether the TextEncoding and TextDecoding intrinsics will be available. NB: This is partial implementation.

pub fn javy_stream_io(&mut self, enable: bool) -> &mut Config

Whether the Javy.IO intrinsic will be available. Disabled by default. Note that it is strongly recommended to target WASI preview 1 when enabling this configuration. To use this configuration with WASI preview 2 or later, you cannot use Javy’s plugin initialization and it will not be compatible for use with the Javy CLI.

pub fn redirect_stdout_to_stderr(&mut self, enable: bool) -> &mut Config

Enables whether the output of console.log will be redirected to stderr.

pub fn gc_threshold(&mut self, bytes: usize) -> &mut Config

The number of bytes to use to trigger garbage collection. The default is usize::MAX.

pub fn memory_limit(&mut self, bytes: usize) -> &mut Config

The limit on the max amount of memory the runtime will use. Default is unlimited.

pub fn max_stack_size(&mut self, bytes: usize) -> &mut Config

The limit on the max size of stack the runtime will use. Default is 256 * 1024.

pub fn log_stream(&mut self, stream: Box<dyn Write>) -> &mut Config

The stream to use for calls to console.log.

pub fn err_stream(&mut self, stream: Box<dyn Write>) -> &mut Config

The stream to use for calls to console.error.

pub fn weak_ref(&mut self, enable: bool) -> &mut Config

Whether the WeakRef instrinsic will be enabled.

pub fn performance(&mut self, enable: bool) -> &mut Config

Whether the Performance intrinsic will be enabled.

Trait Implementations

impl Deref for Config

type Target = Config

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Config

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
