Enum vapcore_light::request::Field

pub enum Field<T> {
    Scalar(T),
    BackReference(usize, usize),
}

An input to a request.

Variants

Scalar(T)

A pre-specified input.

BackReference(usize, usize)

An input which can be resolved later on. (Request index, output index)

Implementations

impl<T> Field<T>

pub fn back_ref(idx: usize, req: usize) -> Self
