Operators for the __richcmp__ method

Variants§

§

Lt = 0

The less than operator.

§

Le = 1

The less than or equal to operator.

§

Eq = 2

The equality operator.

§

Ne = 3

The not equal to operator.

§

Gt = 4

The greater than operator.

§

Ge = 5

The greater than or equal to operator.

Implementations§

source§

impl CompareOp

source

pub fn from_raw(op: c_int) -> Option<Self>

Conversion from the C enum.

source

pub fn matches(&self, result: Ordering) -> bool

Returns if a Rust std::cmp::Ordering matches this ordering query.

Usage example:


#[pyclass]
struct Size {
    size: usize,
}

#[pymethods]
impl Size {
    fn __richcmp__(&self, other: &Size, op: CompareOp) -> bool {
        op.matches(self.size.cmp(&other.size))
    }
}
