Trait LayerFrom 

pub trait LayerFrom<I: ?Sized> {
    type Output;
    type Error;

    // Required method
    fn build(&self, input: &I) -> Result<Self::Output, Self::Error>;
}

Build an extra cell from a reference to the output of a previous layer.

Required Associated Types

type Output

Value produced from input when LayerFrom::build succeeds.

type Error

Error type when LayerFrom::build fails.

Required Methods

fn build(&self, input: &I) -> Result<Self::Output, Self::Error>

Builds using a shared borrow of the upstream layer’s output.

Implementors

impl<I: ?Sized, O, E, F> LayerFrom<I> for LayerFnFrom<F>

where F: Fn(&I) -> Result<O, E>,

type Output = O

type Error = E
