SEXP extensions

Contains all the operation that a normal SEXP could execute.

Required Associated Types

type Data: RType

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

Required Methods

fn as_sexp(&self) -> *mut SEXPREC

get the inner SEXP.

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

where Self: Newable,

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.

Provided Methods

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

1. SEXP.is_correct_type()
2. Self::Data::len(sexp)>0

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

got the read-only data of a SEXP object

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

where <Self as SExt>::Data: RTypeMut, Self: Mutable,

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

1. SEXP.is_correct_type()
2. Self::Data::len(sexp)>0

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

where <Self as SExt>::Data: RTypeMut, Self: Mutable,

got the read-only data of a SEXP object

Object Safety

This trait is not object safe.
