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> ⓘ
Available on crate feature dep_js_sys
only.
pub fn as_f64(&self) -> Option<f64> ⓘ
dep_js_sys
only.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 is_string(&self) -> bool
Available on crate feature dep_js_sys
only.
pub fn is_string(&self) -> bool
dep_js_sys
only.Tests whether this JS value is a JS string.
Sourcepub fn as_string(&self) -> Option<String> ⓘ
Available on crate feature dep_js_sys
only.
pub fn as_string(&self) -> Option<String> ⓘ
dep_js_sys
only.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.

Available on crate feature dep_js_sys
only.
pub fn as_bool(&self) -> Option<bool> ⓘ
