Integer vector methods.

For ALTINTEGER, you must provide EITHER:

• HAS_ELT = true with elt() implementation, OR
• HAS_DATAPTR = true with dataptr() implementation

If neither is provided, R will error at runtime when accessing elements.

Provided Associated Constants

const HAS_ELT: bool = false

Set to true to register elt.

const HAS_GET_REGION: bool = false

Set to true to register get_region.

const HAS_IS_SORTED: bool = false

Set to true to register is_sorted.

const HAS_NO_NA: bool = false

Set to true to register no_na.

const HAS_SUM: bool = false

Set to true to register sum.

const HAS_MIN: bool = false

Set to true to register min.

const HAS_MAX: bool = false

Set to true to register max.

Provided Methods

fn elt(_x: SEXP, _i: R_xlen_t) -> i32

Get element at index.

fn get_region( _x: SEXP, _i: R_xlen_t, _n: R_xlen_t, _buf: &mut [i32], ) -> R_xlen_t

Bulk read elements into buffer.

fn is_sorted(_x: SEXP) -> i32

Sortedness hint.

fn no_na(_x: SEXP) -> i32

NA-free hint.

fn sum(_x: SEXP, _narm: bool) -> SEXP

Optimized sum.

fn min(_x: SEXP, _narm: bool) -> SEXP

Optimized min.

fn max(_x: SEXP, _narm: bool) -> SEXP

Optimized max.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
