Struct v8::value::String

pub struct String(_, _);

A JavaScript string value (ECMA-262, 4.3.17).

Methods

impl String

fn empty(isolate: &Isolate) -> String

fn from_str(isolate: &Isolate, str: &str) -> String

Allocates a new string from UTF-8 data.

fn internalized_from_str(isolate: &Isolate, str: &str) -> String

Allocates a new internalized string from UTF-8 data.

fn length(&self) -> u32

Returns the number of characters in this string.

fn utf8_length(&self) -> u32

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

fn is_one_byte(&self) -> bool

Returns whether this string is known to contain only one byte data.

Does not read the string.

False negatives are possible.

fn contains_only_one_byte(&self) -> bool

Returns whether this string contain only one byte data.

Will read the entire string in some cases.

fn value(&self) -> String

unsafe fn from_raw(isolate: &Isolate, raw: StringRef) -> String

Creates a string from a set of raw pointers.

fn as_raw(&self) -> StringRef

Returns the underlying raw pointer behind this string.

Methods from Deref<Target=Name>

fn get_identity_hash(&self) -> u32

Returns the identity hash for this object.

The current implementation uses an inline property on the object to store the identity hash.

The return value will never be 0. Also, it is not guaranteed to be unique.

fn as_raw(&self) -> NameRef

Returns the underlying raw pointer behind this primitive.
