Struct extendr_api::scalar::Rcplx

#[repr(C)]
pub struct Rcplx(_);

Rcplx is a wrapper for f64 in the context of an R’s complex vector.

Rcplx has a special NA value, obtained from R headers via R_NaReal.

Rcplx has the same footprint as R’s complex value allowing us to use it in zero copy slices.

impl FromIterator<Rcplx> for Complexes

fn from_iter<T: IntoIterator<Item = Rcplx>>(iter: T) -> Self

A more generalised iterator collector for small vectors. Generates a non-ALTREP vector.

impl PartialEq<Rcplx> for Rcplx

fn eq(&self, other: &Rcplx) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
