pub fn evaluate_index(
    index: impl TryInto<i64> + Display,
) -> Result<i64, MathError>

Converts index into an i64 that must be greater or equal than 0 and must fit into an i64.

Parameters:

• index: the index that has to be converted into an i64.

Returns an i64 representation of the index or an error if the index does not fulfill all conditions.

Examples

use qfall_math::utils::index::evaluate_index;

let index = evaluate_index(u32::MAX).unwrap();

Errors and Failures

• Returns a MathError of type OutOfBounds if either the index is negative or it does not fit into an i64.
