Trait IndexValue 

pub trait IndexValue: Copy {
    // Required method
    fn position(self) -> i64;

    // Provided method
    fn bounds(values: &[Self]) -> (i64, i64) { ... }
}

A value that names a position along an axis: a Boolean or an integer. A float index value names the whole number it equals within the comparison tolerance, which crate::structure::float_position reads before any table holds it.

Required Methods

fn position(self) -> i64

The position the value names, where a negative one counts back from the end.

Provided Methods

fn bounds(values: &[Self]) -> (i64, i64)

The least and greatest positions that values name, which mean nothing where values is empty.

Dyn Compatibility

This trait is not dyn compatible.

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