Trait RPartialOrd 

pub trait RPartialOrd {
    // Required method
    fn partial_cmp(&self, other: &Self) -> Option<i32>;
}

Adapter trait for std::cmp::PartialOrd.

Provides partial ordering comparison for R, handling incomparable values. Automatically implemented for any type that implements PartialOrd.

Methods

• partial_cmp(&self, other: &Self) - Returns Some(-1/0/1) or None

Example

// f64 has partial ordering (NaN is not comparable)
#[derive(PartialOrd, PartialEq, ExternalPtr)]
struct MyFloat(f64);

#[miniextendr]
impl RPartialOrd for MyFloat {}

Required Methods

fn partial_cmp(&self, other: &Self) -> Option<i32>

Compare with another value, returning None if incomparable.

Returns:

• Some(-1) if self < other
• Some(0) if self == other
• Some(1) if self > other
• None if values are incomparable (maps to NA in R)

Dyn Compatibility

This trait is not dyn compatible.

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