Struct rmin::SEXP

pub struct SEXP<T: RType> { /* private fields */ }

ReadOnly SEXP, should not be changed.

This is the preferred way for accept ffi values Since R marked the input values as readonly.

Trait Implementations

impl<T: Clone + RType> Clone for SEXP<T>

fn clone(&self) -> SEXP<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: RType> From<Owned<T>> for SEXP<T>

fn from(s: Owned<T>) -> Self

Converts to this type from the input type.

impl<T: RType> Index<usize> for SEXP<T>

where SEXP<T>: SExt,

type Output = <<SEXP<T> as SExt>::Data as RType>::Data

The returned type after indexing.

fn index(&self, index: usize) -> &<<SEXP<T> as SExt>::Data as RType>::Data

Performs the indexing (container[index]) operation.

impl<T: RTypeMut> IndexMut<usize> for SEXP<T>

where SEXP<T>: Mutable, <SEXP<T> as SExt>::Data: RTypeMut,

fn index_mut( &mut self, index: usize ) -> &mut <<SEXP<T> as SExt>::Data as RType>::Data

Performs the mutable indexing (container[index]) operation.

impl<T: RType> SExt for SEXP<T>

type Data = T

SEXP Associated data, normally double->f64, integer->i32, logical->u32, character->u8, Other data might be added in the future.

fn as_sexp(&self) -> *mut SEXPREC

get the inner SEXP.

fn new(len: <Self::Data as RType>::New) -> Self

allocate a new SEXP object with length for u8 (CHARcrate::libR::SEXP), new with length is not allowed thus CHARcrate::libR::SEXP accept a String object.

fn is_correct_type(&self) -> bool

check whether the data has the desired type

fn len(&self) -> usize

get length of this SEXP.

unsafe fn data_unchecked(&self) -> &[<Self::Data as RType>::Data]

got the read-only data of a SEXP object SAFETY: caller should ensure this SEXP has data with

fn data(&self) -> &[<Self::Data as RType>::Data]

got the read-only data of a SEXP object
