    scope: &mut impl ToLocal<'sc>,
    buffer: &[u8],
    new_type: NewStringType
) -> Option<Local<'sc, String>>

pub fn length(&self) -> usize

Returns the number of characters (UTF-16 code units) in this string.

pub fn utf8_length(&self, scope: &mut impl InIsolate) -> usize

Returns the number of bytes in the UTF-8 encoded representation of this string.

    scope: &mut impl InIsolate,
    buffer: &mut [u8],
    nchars_ref: Option<&mut usize>,
    options: WriteOptions
) -> usize

Methods from Deref<Target = 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_string(&self) -> bool

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

pub fn is_array(&self) -> bool

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

Returns true if this value is a function.

pub fn is_object(&self) -> bool

Returns true if this value is an object.

pub fn is_number(&self) -> bool
