[][src]Struct rusty_v8_m::External

#[repr(C)]pub struct External(_);

A JavaScript value that wraps a C++ void*. This type of value is mainly used to associate C++ data structures with JavaScript objects.

Methods from Deref<Target = Value>

pub fn is_undefined(&self) -> bool[src]

Returns true if this value is the undefined value. See ECMA-262 4.3.10.

pub fn is_null(&self) -> bool[src]

Returns true if this value is the null value. See ECMA-262 4.3.11.

pub fn is_null_or_undefined(&self) -> bool[src]

Returns true if this value is either the null or the undefined value. See ECMA-262 4.3.11. and 4.3.12

pub fn is_true(&self) -> bool[src]

Returns true if this value is true. This is not the same as BooleanValue(). The latter performs a conversion to boolean, i.e. the result of Boolean(value) in JS, whereas this checks value === true.

pub fn is_false(&self) -> bool[src]

Returns true if this value is false. This is not the same as !BooleanValue(). The latter performs a conversion to boolean, i.e. the result of !Boolean(value) in JS, whereas this checks value === false.

pub fn is_name(&self) -> bool[src]

Returns true if this value is a symbol or a string. This is equivalent to typeof value === 'string' || typeof value === 'symbol' in JS.

pub fn is_string(&self) -> bool[src]

Returns true if this value is an instance of the String type. See ECMA-262 8.4.

Returns true if this value is a symbol. This is equivalent to typeof value === 'symbol' in JS.

Returns true if this value is a function.

Returns true if this value is an array. Note that it will return false for an Proxy for an array.

pub fn is_object(&self) -> bool[src]

Returns true if this value is an object.

pub fn is_big_int(&self) -> bool[src]

Returns true if this value is a bigint. This is equivalent to typeof value === 'bigint' in JS.
