Implementations

impl Value

pub fn is_undefined(&self) -> bool

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

pub fn is_null(&self) -> bool

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

pub fn is_null_or_undefined(&self) -> bool

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

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.

This operation is used to compare values for the purpose of insertion into a Set, or determining whether Map keys are equivalent. Its semantics are almost the same as strict_equals() and same_value(), with the following important distinctions:

• It considers NaN equal to NaN (unlike strict_equals()).
• It considers -0 equal to 0 (unlike same_value()).
