Module sexp_types 

Core type vocabulary for R values: SEXPTYPE, R_xlen_t, Rcomplex, RLogical, Rboolean, RNativeType, cetype_t. Core type vocabulary for R values: SEXPTYPE, R_xlen_t, Rbyte, Rcomplex, RLogical, Rboolean, cetype_t, R_CFinalizer_t, and the RNativeType marker trait + impls.

These types are the bridge between raw R FFI (in crate::sys) and the safe Rust API on SEXP (in crate::sexp and crate::sexp_ext). Most user code reaches them via crate::prelude.

Re-exports

pub use cetype_t::CE_UTF8;

Structs

RLogical

R’s logical element type (the contents of a LGLSXP vector).

Rcomplex

R’s complex scalar layout (Rcomplex).

Enums

Rboolean

Binary boolean used by many R C APIs.

SEXPTYPE

R S-expression tag values (SEXPTYPE).

cetype_t

Character encoding tag used by CHARSXP constructors.

Traits

RNativeType

Marker trait for types that correspond to R’s native vector element types.

Type Aliases

R_CFinalizer_t

C finalizer callback signature used by external pointers.

R_xlen_t

R’s extended vector length type (R_xlen_t).

Rbyte

R byte element type used by RAWSXP.
