Struct AsNamedVector 

pub struct AsNamedVector<T>(pub T);

Wrap a tuple pair collection and convert it to a named atomic R vector (INTSXP, REALSXP, LGLSXP, RAWSXP, or STRSXP).

Preserves insertion order and allows duplicate names (sequence semantics). Values must be homogeneous and implement AtomicElement.

Supported input types

Input	Bounds
Vec<(K, V)>	K: AsRef<str>, V: AtomicElement
[(K, V); N]	K: AsRef<str>, V: AtomicElement
&[(K, V)]	K: AsRef<str>, V: Clone + AtomicElement

Example

#[miniextendr]
fn make_scores() -> AsNamedVector<Vec<(&str, f64)>> {
    AsNamedVector(vec![("alice", 95.0), ("bob", 87.5)])
}
// In R: make_scores() returns c(alice = 95.0, bob = 87.5)

Tuple Fields

0: T

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
