[−][src]Struct js_sys::TypeError
The TypeError object represents an error when a value is not of the expected type.
Methods
impl TypeError
[src]
pub fn new(message: &str) -> TypeError
[src]
The TypeError object represents an error when a value is not of the expected type.
Methods from Deref<Target = Error>
pub fn message(&self) -> JsString
[src]
The message property is a human-readable description of the error.
pub fn set_message(&self, message: &str)
[src]
pub fn name(&self) -> JsString
[src]
The name property represents a name for the type of error. The initial value is "Error".
pub fn to_string(&self) -> JsString
[src]
The toString() method returns a string representing the specified Error object

impl RefFromWasmAbi for TypeError
[src]
type Abi = <JsValue as RefFromWasmAbi>::Abi
The wasm ABI type references to Self
are recovered from.
type Anchor = ManuallyDrop<TypeError>
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
