Module value 

Boa’s ECMAScript Value implementation.

Javascript values, utility methods and conversion between Javascript values and Rust values.

Macros

js_object

The js_value! macro creates a JsValue instance based on a JSON-like DSL.

js_value

Create a JsObject object from a simpler DSL that resembles JSON.

Structs

Convert

A wrapper type that allows converting a JsValue to a specific type. This is useful when you want to convert a JsValue to a Rust type.

JsValue

A generic JavaScript value. This can be any ECMAScript language valid value.

ValueDisplay

This object is used for displaying a Value.

Enums

AbstractRelation

The result of the Abstract Relational Comparison.

IntegerOrInfinity

Represents the result of the ToIntegerOrInfinity operation

JsVariant

A non-mutable variant of a JsValue. Represents either a primitive value (bool, f64, i32) or a reference to a heap allocated value (JsString, JsSymbol).

Nullable

A value that can be null in JavaScript, but not undefined.

Numeric

Numeric value which can be of two types Number, BigInt.

PreferredType

The preferred type to convert an object to a primitive Value.

Type

Possible types of values as defined at https://tc39.es/ecma262/#sec-typeof-operator.

Traits

TryFromJs

This trait adds a fallible and efficient conversions from a JsValue to Rust types.

TryIntoJs

This trait adds a conversions from a Rust Type into JsValue.

Derive Macros

TryFromJs

Derives the TryFromJs trait, with the #[boa()] attribute.

TryIntoJs

Derives the TryIntoJs trait, with the #[boa()] attribute.
