Trait IndexOrd 

pub trait IndexOrd<V> {
    // Required methods
    fn index_cmp(&self, idx: usize, elem: &V) -> VortexResult<Option<Ordering>>;
    fn index_len(&self) -> usize;

    // Provided methods
    fn index_lt(&self, idx: usize, elem: &V) -> VortexResult<bool> { ... }
    fn index_le(&self, idx: usize, elem: &V) -> VortexResult<bool> { ... }
    fn index_gt(&self, idx: usize, elem: &V) -> VortexResult<bool> { ... }
    fn index_ge(&self, idx: usize, elem: &V) -> VortexResult<bool> { ... }
}

Required Methods

fn index_cmp(&self, idx: usize, elem: &V) -> VortexResult<Option<Ordering>>

PartialOrd of the value at index idx with elem. For example, if self[idx] > elem, return Some(Greater).

fn index_len(&self) -> usize

Get the length of the underlying ordered collection

Provided Methods

fn index_lt(&self, idx: usize, elem: &V) -> VortexResult<bool>

fn index_le(&self, idx: usize, elem: &V) -> VortexResult<bool>

fn index_gt(&self, idx: usize, elem: &V) -> VortexResult<bool>

fn index_ge(&self, idx: usize, elem: &V) -> VortexResult<bool>

Dyn Compatibility

This trait is dyn compatible.

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