Trait ADKey 

pub trait ADKey:
    Clone
    + Debug
    + Hash
    + Eq
    + Send
    + Sync
    + 'static {
    // Required method
    fn tangent_of(&self, pass: DiffPassId) -> Self;
}

Constraint on GraphOperation::InputKey for AD use.

tidu uses this trait to generate tangent input keys during crate::linearize.

Examples

use tidu::{ADKey, DiffPassId};

#[derive(Clone, Debug, PartialEq, Eq, Hash)]
enum MyKey {
    User(String),
    Tangent { of: Box<MyKey>, pass: DiffPassId },
}

impl ADKey for MyKey {
    fn tangent_of(&self, pass: DiffPassId) -> Self {
        MyKey::Tangent {
            of: Box::new(self.clone()),
            pass,
        }
    }
}

Required Methods

fn tangent_of(&self, pass: DiffPassId) -> Self

Create a tangent input key derived from this key. pass is a unique identifier for the linearize call.

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.
