Trait LogosIndex 

pub trait LogosIndex<I> {
    type Output;

    // Required method
    fn logos_get(&self, index: I) -> Self::Output;
}

Immutable element access by index.

Provides 1-based indexing for Logos collections. Index 1 refers to the first element, index 2 to the second, and so on.

Examples

use logicaffeine_data::LogosIndex;

let v = vec!["a", "b", "c"];
assert_eq!(v.logos_get(1i64), "a");  // 1-based!
assert_eq!(v.logos_get(3i64), "c");

Panics

Panics if the index is less than 1 or greater than the collection length.

Required Associated Types

type Output

The type of element returned by indexing.

Required Methods

fn logos_get(&self, index: I) -> Self::Output

Get the element at the given index.

Implementations on Foreign Types
