Trait SumFromStorage 

pub trait SumFromStorage: Sized {
    // Required method
    fn sum_from_storage(storage: &Storage) -> Self;
}

Types that can be computed as the result of a reduction over Storage.

This lets callers write let s: T = tensor.sum(); without matching on the storage variant. Implemented for f64 and Complex64.

Examples

use tensor4all_tensorbackend::{Storage, SumFromStorage};

let s = Storage::from_dense_col_major(vec![1.0_f64, 2.0, 3.0], &[3]).unwrap();
let total: f64 = f64::sum_from_storage(&s);
assert!((total - 6.0).abs() < 1e-10);

Required Methods

fn sum_from_storage(storage: &Storage) -> Self

Compute the sum of all elements in the storage.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
