Trait TryComputer 

pub trait TryComputer<__Context__, Code, Input>: IsProviderFor<TryComputerComponent, __Context__, (Code, Input)>
where
    __Context__: HasErrorType,
{
    type Output;

    // Required method
    fn try_compute(
        __context__: &__Context__,
        _code: PhantomData<Code>,
        input: Input,
    ) -> Result<Self::Output, <__Context__ as HasErrorType>::Error>;
}

Required Associated Types

type Output

Required Methods

fn try_compute( __context__: &__Context__, _code: PhantomData<Code>, input: Input, ) -> Result<Self::Output, <__Context__ as HasErrorType>::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.
