[src]
pub fn value(&self) -> f64
[src]
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_string(&self) -> bool
[src]
Returns true if this value is an instance of the String type. See ECMA-262 8.4.
pub fn is_array(&self) -> bool
[src]
Returns true if this value is an array. Note that it will return false for an Proxy for an array.
pub fn is_function(&self) -> bool
[src]
Returns true if this value is a function.
pub fn is_object(&self) -> bool
[src]
Returns true if this value is an object.
pub fn is_number(&self) -> bool
[src]
Returns true if this value is a number.
pub fn strict_equals<'sc>(&self, that: Local<'sc, Value>) -> bool
[src]
