Trait TryComputerRef 

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

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

Required Associated Types

type Output

Required Methods

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