pub fn as_f64(&self) -> Option<f64>
[src]
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
.
pub fn is_string(&self) -> bool
[src]
Tests whether this JS value is a JS string.
pub fn as_string(&self) -> Option<String>
[src]
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
.
pub fn as_bool(&self) -> Option<bool>
[src]
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
.
pub fn is_null(&self) -> bool
[src]
Tests whether this JS value is null
pub fn is_undefined(&self) -> bool
[src]
Tests whether this JS value is undefined
pub fn is_symbol(&self) -> bool
[src]
Tests whether the type of this JS value is symbol
pub fn is_object(&self) -> bool
[src]
Tests whether typeof self == "object" && self !== null
.
pub fn is_function(&self) -> bool
[src]
Tests whether the type of this JS value is function
.

type Anchor = ManuallyDrop<JsGrid>
The type that holds the reference to Self
for the duration of the invocation of the function that has an &Self
parameter. This is required to ensure that the lifetimes don't persist beyond one function call, and so that they remain anonymous. Read more
