Trait IntoKeyedValueAndGrad

pub trait IntoKeyedValueAndGrad<'a, Arr, Args, Err>
where
    Arr: AsRef<Array>,
    Args: Clone,
{
    // Required method
    fn into_keyed_value_and_grad(
        self,
    ) -> impl FnMut(KeyedParameters<Arr>, Args) -> Result<(Vec<Array>, KeyedGrad)> + 'a;
}

Similar to [IntoValueAndGrad] but for functions that take a hashmap of parameters.

Required Methods

fn into_keyed_value_and_grad( self, ) -> impl FnMut(KeyedParameters<Arr>, Args) -> Result<(Vec<Array>, KeyedGrad)> + 'a

Convert the function/closure into a closure that computes the value and gradient.

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.

Implementors
