Struct RSymbol 

pub struct RSymbol {
    sexp: SEXP,
}

A safe wrapper around R symbols (SYMSXP).

R symbols are interned strings used as variable and function names. They are never garbage collected, so RSymbol does not need GC protection.

Example

let sym = RSymbol::new("paste0");
// sym.as_sexp() is a SYMSXP that can be used in call construction

Fields

sexp: SEXP

Implementations

impl RSymbol

pub unsafe fn new(name: &str) -> Self

Create or retrieve an interned R symbol.

Safety

Must be called from the R main thread.

Panics

Panics if name contains a null byte.

pub unsafe fn from_cstr(name: &CStr) -> Self

Create a symbol from a C string literal.

This avoids the allocation needed by new when you have a &CStr available (e.g., from c"name" literals).

Safety

Must be called from the R main thread.

pub fn as_sexp(&self) -> SEXP

Get the underlying SEXP.
