Struct JsRef 

pub struct JsRef(/* private fields */);

Implementations

impl JsRef

pub const NULL: JsRef

The null JS value constant.

pub const UNDEFINED: JsRef

The undefined JS value constant.

pub const TRUE: JsRef

The true JS value constant.

pub const FALSE: JsRef

The false JS value constant.

pub const fn is_special_value(self) -> bool

pub const fn is_owned_heap_ref(self) -> bool

pub const fn into_abi(self) -> u32

pub const fn from_abi(abi: u32) -> JsRef

pub fn next_borrowed_ref() -> JsRef

Reserve a handle to the next borrowed JS reference.

Borrowed references occupy the borrow stack (indices 1-127) rather than a heap slot; JS puts the value on its borrow stack without sending an id, so Rust syncs by reserving the matching handle here.

pub fn drop_js_object(self)

Release this JS heap object.

pub fn dispose_js_rust_function(self)

Dispose the JS wrapper for the Rust callback behind this reference.

pub fn invalidate_js_rust_function(self)

Mark the JS wrapper for the Rust callback behind this reference as unusable.

impl Eq for JsRef

impl Hash for JsRef

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl JsRefEncode for JsRef

fn js_ref(&self) -> JsRef

impl PartialEq for JsRef

fn eq(&self, other: &JsRef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
