Dart closure that can be called from Rust.

Implementations

impl<T> Function<T>

pub fn new(cb: DartOpaque) -> Self

impl Function<()>

pub fn call0(&self)

Calls the underlying Dart closure.

impl<T: Into<DartValue>> Function<T>

pub fn call1(&self, arg: T)

Calls the underlying Dart closure with the provided argument.

Trait Implementations

impl<T: Debug> Debug for Function<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Drop for Function<T>

fn drop(&mut self)
