impl BigInt64Array
sourcepub unsafe fn view(rust: &[i64]) -> BigInt64Array
pub unsafe fn view(rust: &[i64]) -> BigInt64Array
Creates a JS typed array which is a view into wasm’s linear memory at the slice specified.
This function returns a new typed array which is a view into wasm’s memory. This view does not copy the underlying data.
§Unsafety
Views into WebAssembly memory are only valid so long as the
backing buffer isn’t resized in JS. Once this function is called
any future calls to Box::new
(or malloc of any form) may cause
the returned value here to be invalidated. Use with caution!
Additionally the returned object can be safely mutated but the input slice isn’t guaranteed to be mutable.
Finally, the returned object is disconnected from the input slice’s lifetime, so there’s no guarantee that the data is read at the right time.
sourcepub unsafe fn view_mut_raw(ptr: *mut i64, length: usize) -> BigInt64Array
pub unsafe fn view_mut_raw(ptr: *mut i64, length: usize) -> BigInt64Array
Creates a JS typed array which is a view into wasm’s linear memory at the specified pointer with specified length.
This function returns a new typed array which is a view into wasm’s memory. This view does not copy the underlying data.
§Unsafety
Views into WebAssembly memory are only valid so long as the
backing buffer isn’t resized in JS. Once this function is called
any future calls to Box::new
(or malloc of any form) may cause
the returned value here to be invalidated. Use with caution!
Additionally the returned object can be safely mutated, the changes are guaranteed to be reflected in the input array.
sourcepub unsafe fn raw_copy_to_ptr(&self, dst: *mut i64)
pub unsafe fn raw_copy_to_ptr(&self, dst: *mut i64)
Copy the contents of this JS typed array into the destination Rust pointer.
This function will efficiently copy the memory from a typed array into this Wasm module’s own linear memory, initializing the memory destination provided.
§Unsafety
This function requires dst
to point to a buffer
large enough to fit this array’s contents.
sourcepub fn copy_to(&self, dst: &mut [i64])
pub fn copy_to(&self, dst: &mut [i64])
Copy the contents of this JS typed array into the destination Rust slice.
This function will efficiently copy the memory from a typed array into this Wasm module’s own linear memory, initializing the memory destination provided.
§Panics
This function will panic if this typed array’s length is
different than the length of the provided dst
array.
sourcepub fn copy_from(&self, src: &[i64])
pub fn copy_from(&self, src: &[i64])
Copy the contents of the source Rust slice into this JS typed array.
This function will efficiently copy the memory from within the Wasm module’s own linear memory to this typed array.
§Panics
This function will panic if this typed array’s length is
different than the length of the provided src
array.
Methods from Deref<Target = Object>§
sourcepub fn constructor(&self) -> Function
pub fn constructor(&self) -> Function
The constructor property returns a reference to the Object
constructor
function that created the instance object.
sourcepub fn has_own_property(&self, property: &JsValue) -> bool
pub fn has_own_property(&self, property: &JsValue) -> bool
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
sourcepub fn is_prototype_of(&self, value: &JsValue) -> bool
pub fn is_prototype_of(&self, value: &JsValue) -> bool
The isPrototypeOf()
method checks if an object exists in another
object’s prototype chain.
sourcepub fn property_is_enumerable(&self, property: &JsValue) -> bool
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
sourcepub fn to_locale_string(&self) -> JsString
pub fn to_locale_string(&self) -> JsString
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
sourcepub fn to_string(&self) -> JsString
pub fn to_string(&self) -> JsString
The toString()
method returns a string representing the object.
Methods from Deref<Target = JsValue>§
pub const NULL: JsValue = _
pub const UNDEFINED: JsValue = _
pub const TRUE: JsValue = _
pub const FALSE: JsValue = _
sourcepub fn as_f64(&self) -> Option<f64>
pub fn as_f64(&self) -> Option<f64>
Returns the f64
value of this JS value if it’s an instance of a
number.
If this JS value is not an instance of a number then this returns
None
.
sourcepub fn as_string(&self) -> Option<String>
pub fn as_string(&self) -> Option<String>
If this JS value is a string value, this function copies the JS string
value into Wasm linear memory, encoded as UTF-8, and returns it as a
Rust String
.
To avoid the copying and re-encoding, consider the
JsString::try_from()
function from js-sys
instead.
If this JS value is not an instance of a string or if it’s not valid
utf-8 then this returns None
.
§UTF-16 vs UTF-8
JavaScript strings in general are encoded as UTF-16, but Rust strings
are encoded as UTF-8. This can cause the Rust string to look a bit
different than the JS string sometimes. For more details see the
documentation about the str
type which contains a few
caveats about the encodings.
sourcepub fn as_bool(&self) -> Option<bool>
pub fn as_bool(&self) -> Option<bool>
Returns the bool
value of this JS value if it’s an instance of a
boolean.
If this JS value is not an instance of a boolean then this returns
None
.
sourcepub fn is_undefined(&self) -> bool
pub fn is_undefined(&self) -> bool
Tests whether this JS value is undefined
sourcepub fn is_function(&self) -> bool
pub fn is_function(&self) -> bool
Tests whether the type of this JS value is function
.
sourcepub fn js_in(&self, obj: &JsValue) -> bool
pub fn js_in(&self, obj: &JsValue) -> bool
Applies the binary in
JS operator on the two JsValue
s.
sourcepub fn loose_eq(&self, other: &JsValue) -> bool
pub fn loose_eq(&self, other: &JsValue) -> bool
Compare two JsValue
s for equality, using the ==
operator in JS.
sourcepub fn unsigned_shr(&self, rhs: &JsValue) -> u32
pub fn unsigned_shr(&self, rhs: &JsValue) -> u32

s.
sourcepub fn checked_div(&self, rhs: &JsValue) -> JsValue
pub fn checked_div(&self, rhs: &JsValue) -> JsValue

JS operator on two JsValue
s, catching and returning any RangeError
thrown.
sourcepub fn pow(&self, rhs: &JsValue) -> JsValue
pub fn pow(&self, rhs: &JsValue) -> JsValue
Applies the binary **
JS operator on the two JsValue
s.
sourcepub fn lt(&self, other: &JsValue) -> bool
pub fn lt(&self, other: &JsValue) -> bool
Applies the binary <
JS operator on the two JsValue
s.
sourcepub fn le(&self, other: &JsValue) -> bool
pub fn le(&self, other: &JsValue) -> bool
Applies the binary <=
JS operator on the two JsValue
s.
sourcepub fn ge(&self, other: &JsValue) -> bool
pub fn ge(&self, other: &JsValue) -> bool
Applies the binary >=
JS operator on the two JsValue
s.
sourcepub fn gt(&self, other: &JsValue) -> bool
pub fn gt(&self, other: &JsValue) -> bool
Applies the binary >
JS operator on the two JsValue
s.

JS operator on a JsValue
. Can throw.
