Struct Record

pub struct Record<K, V> { /* private fields */ }

Web‑IDL record<K, V> wrapper.

Implementations

impl<K, V> Record<K, V>

pub fn set(&self, item: K, val: V)

where Val: From<K> + From<V>,

pub fn get(&self, item: K) -> V

where Val: From<K> + From<V>, V: FromVal,

pub fn has(&self, item: K) -> bool

where Val: From<K>,

Returns whether a value exists in the sequence.

Methods from Deref<Target = Val>

pub fn get<T>(&self, prop: T) -> Val

where T: Into<Val>,

pub fn has<T>(&self, prop: T) -> bool

where T: Into<Val>,

Checks whether a property prop exists

pub fn has_own_property(&self, prop: &str) -> bool

Checks whether a non-inherited property prop exists

pub fn type_of(&self) -> String

Gets the typeof the underlying js object

pub fn at<T>(&self, idx: T) -> Val

where T: Into<Val>,

Gets the element at index idx. Assumes the underlying js type is indexable

pub fn to_vec<V>(&self) -> Vec<V>

where V: FromVal,

pub fn call(&self, f: &str, args: &[Val]) -> Val

Calls the method f with args, can return an undefined js value

pub fn new(&self, args: &[Val]) -> Val

Calls the object’s constructor with args constructing a new object

pub fn invoke(&self, args: &[Val]) -> Val

Invokes the function object with args, can return an undefined js value

pub fn await_(&self) -> Val

Awaits the invoked function object

pub fn instanceof(&self, v: Val) -> bool

Checks whether this Val is an instanceof v

pub fn is_number(&self) -> bool

pub fn is_string(&self) -> bool

pub fn is_null(&self) -> bool

pub fn is_undefined(&self) -> bool

pub fn is_error(&self) -> bool

pub fn is_function(&self) -> bool

pub fn as_<T>(&self) -> T

where T: FromVal,

Trait Implementations

impl<K, V> AsMut<Val> for Record<K, V>

fn as_mut(&mut self) -> &mut Val

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

impl<K, V> AsRef<Val> for Record<K, V>

fn as_ref(&self) -> &Val

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

impl<K: Clone, V: Clone> Clone for Record<K, V>

fn clone(&self) -> Record<K, V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for Record<K, V>

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

Formats the value using the given formatter.

impl<K, V> Deref for Record<K, V>

type Target = Val

The resulting type after dereferencing.

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

Dereferences the value.

impl<K, V> DerefMut for Record<K, V>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<K, V> From<Record<K, V>> for TypedMap<K, V>

where K: FromVal + Into<Val>, V: FromVal + Into<Val>,

fn from(rec: Record<K, V>) -> Self

Converts to this type from the input type.

impl<K, V> From<Record<K, V>> for TypedWeakMap<K, V>

where K: FromVal + Into<Val>, V: FromVal + Into<Val>,

fn from(rec: Record<K, V>) -> Self

Converts to this type from the input type.

impl<K, V> From<Record<K, V>> for Val

fn from(x: Record<K, V>) -> Val

Converts to this type from the input type.

impl<K, V> FromVal for Record<K, V>

fn from_val(v: &Val) -> Self

Creates a Val object from another

fn take_ownership(v: Handle) -> Self

Takes the ownership of a handle

fn as_handle(&self) -> Handle

Returns the raw js handle

impl<K: PartialEq, V: PartialEq> PartialEq for Record<K, V>

fn eq(&self, other: &Record<K, V>) -> 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.

impl<K: PartialOrd, V: PartialOrd> PartialOrd for Record<K, V>

fn partial_cmp(&self, other: &Record<K, V>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
