Struct rquickjs_core::Array

#[repr(transparent)]
pub struct Array<'js>(_);

Rust representation of a javascript object optimized as an array.

Javascript array’s are objects and can be used as such. However arrays in quickjs are optimized when they do not have any holes. This value represents such a optimized array.

Trait Implementations

impl<'js> AsRef<Value<'js>> for Array<'js>

fn as_ref(&self) -> &Value<'js>

Converts this type into a shared reference of the (usually inferred) input type.

impl<'js> Clone for Array<'js>

fn clone(&self) -> Array<'js>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

impl<'js> Debug for Array<'js>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'js> Deref for Array<'js>

type Target = Value<'js>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'js> From<Array<'js>> for Value<'js>

fn from(value: Array<'js>) -> Self

Converts to this type from the input type.

impl<'js, A> FromIteratorJs<'js, A> for Array<'js> where
    A: IntoJs<'js>,

impl<'js> IntoAtom<'js> for Array<'js>

fn into_atom(self, ctx: Ctx<'js>) -> Atom<'js>

impl<'js> IntoIterator for Array<'js>

type Item = Result<Value<'js>, Error>

The type of the elements being iterated over.

type IntoIter = ArrayIter<'js, Value<'js>>

Which kind of iterator are we turning this into?

impl<'js> PartialEq<Array<'js>> for Array<'js>

fn eq(&self, other: &Array<'js>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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