Enum abi_stable::std_types::RCmpOrdering

#[repr(u8)]pub enum RCmpOrdering {
    Less,
    Equal,
    Greater,
}

Ffi-safe equivalent of std::cmp::Ordering.

Example

This defines an extern function,which compares a slice to another.

use abi_stable::{
    std_types::{RCmpOrdering,RSlice},
    sabi_extern_fn,
};
use std::cmp::Ord;


#[sabi_extern_fn]
pub fn compare_slices<T>(l:RSlice<'_,T>, r:RSlice<'_,T>)->RCmpOrdering
where
    T:Ord
{
    l.cmp(&r)
     .into()
}

Variants

Less

Equal

Greater

Implementations

impl RCmpOrdering

pub fn into_ordering(self) -> Ordering

Converts this RCmpOrdering into a std::cmp::Ordering;

Example

use abi_stable::std_types::RCmpOrdering;
use std::cmp::Ordering;
 

assert_eq!( RCmpOrdering::Less.into_ordering(), Ordering::Less );
assert_eq!( RCmpOrdering::Equal.into_ordering(), Ordering::Equal );
assert_eq!( RCmpOrdering::Greater.into_ordering(), Ordering::Greater );
