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".
