Trait TryGetFut 

pub trait TryGetFut {
    type Input;
    type Output;
    type Aux;
    type Error;

    // Required method
    fn try_get_fut<'a>(
        self,
        input: &'a mut Self::Input,
    ) -> Result<(impl 'a + Future<Output = Self::Output>, Self::Aux), Self::Error>;
}

A functor trait for trying to get a complex future from an input.

Required Associated Types

type Input

The input type of the functor. Will be returned to the caller if unsuccessful.

type Output

The output type of the resulting future if successful.

type Aux

Auxiliary data that should be returned to the caller if successful.

type Error

Error data that should be returned to the caller if unsuccessful.

Required Methods

fn try_get_fut<'a>( self, input: &'a mut Self::Input, ) -> Result<(impl 'a + Future<Output = Self::Output>, Self::Aux), Self::Error>

The functor applicator.

Takes a mutable reference some input and returns either a future and some auxiliary data or an error.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
