Struct extendr_api::scalar::Rint[][src]

pub struct Rint(pub i32);
Expand description

Rint is a wrapper for i32 in the context of an R’s integer vector.

Rint can have a value between i32::MIN+1 and i32::MAX

The value i32::MIN is used as “NA”.

Rint has the same footprint as an i32 value allowing us to use it in zero copy slices.

0: i32
