Trait ROrd 

pub trait ROrd {
    // Required method
    fn cmp(&self, other: &Self) -> i32;
}

Adapter trait for std::cmp::Ord.

Provides total ordering comparison for R sorting operations. Automatically implemented for any type that implements Ord.

Methods

• cmp(&self, other: &Self) - Returns -1, 0, or 1

Example

#[derive(Ord, PartialOrd, Eq, PartialEq, ExternalPtr)]
struct Priority(u32);

#[miniextendr]
impl ROrd for Priority {}

Required Methods

fn cmp(&self, other: &Self) -> i32

Compare with another value.

Returns:

• -1 if self < other
• 0 if self == other
• 1 if self > other

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
