Trait TryCastJsInto 

pub trait TryCastJsInto<T>
where
    T: TryCastFromJs,
{
    type Error: From<Error>;

    // Required methods
    fn try_into_cast(&self) -> Result<Cast<'_, T>, Self::Error>;
    fn try_into_owned(&self) -> Result<T, Self::Error>;
}

Inverse of TryCastFromJs, allowing a source value (such as a JsValue) to be cast into a target Rust type T that implements TryCastFromJs.

Required Associated Types

type Error: From<Error>

Error type returned by the conversion, convertible from Error.

Required Methods

fn try_into_cast(&self) -> Result<Cast<'_, T>, Self::Error>

Attempt to cast self into a Cast wrapping the target type T.

fn try_into_owned(&self) -> Result<T, Self::Error>

Attempt to cast self into an owned value of the target type T.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<T> TryCastJsInto<T> for JsValue

where T: TryCastFromJs, <T as TryCastFromJs>::Error: From<Error>,

type Error = <T as TryCastFromJs>::Error
