Trait IntoValueAndGrad

pub trait IntoValueAndGrad<'a, Err> {
    // Required method
    fn into_value_and_grad(
        self,
        argument_numbers: impl IntoOption<&'a [i32]>,
    ) -> impl FnMut(&[Array]) -> Result<(Vec<Array>, Vec<Array>)> + 'a;
}

Trait for functions/closures that can be converted into a closure that computes the value and gradient.

Required Methods

fn into_value_and_grad( self, argument_numbers: impl IntoOption<&'a [i32]>, ) -> impl FnMut(&[Array]) -> Result<(Vec<Array>, Vec<Array>)> + '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

impl<'a, F> IntoValueAndGrad<'a, ()> for F

where F: FnMut(&[Array]) -> Vec<Array> + 'a,

impl<'a, F> IntoValueAndGrad<'a, Exception> for F

where F: FnMut(&[Array]) -> Result<Vec<Array>> + 'a,
