Trait IndexInt 

pub trait IndexInt:
    Copy
    + Send
    + Sync
    + 'static {
    // Required method
    fn to_usize(self) -> usize;
}

Trait for index element types.

All indices within a single CachedFunction must use the same integer type. Implemented for u8, u16, u32, and usize. Use u8 for quantics TCI where local_dim = 2.

Examples

use tensor4all_tcicore::{IndexInt, CachedFunction};

// Using u8 indices for quantics (local_dim = 2)
let cf = CachedFunction::new(
    |idx: &[u8]| idx.iter().map(|&x| x as usize).sum::<usize>(),
    &[2, 2, 2],
).unwrap();
assert_eq!(cf.eval(&[1u8, 0, 1]), 2);

Required Methods

fn to_usize(self) -> usize

Convert this index element to usize.

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.
