Struct Bool 

pub struct Bool(pub i32);

Bool is a wrapper for i32 in the context of an R’s tristate boolean. It can be TRUE, FALSE or NA_LOGICAL.

Tuple Fields

0: i32

Implementations

impl Bool

pub fn to_bool(&self) -> bool

Convert this Bool to a bool. Note NA will be true.

pub fn from_bool(val: bool) -> Self

Convert this construct a Bool from a rust boolean.

pub fn is_true(&self) -> bool

Test if TRUE

pub fn is_false(&self) -> bool

Test if FALSE

Trait Implementations

impl<'a> AsTypedSlice<'a, Bool> for Robj

where Self: 'a,

fn as_typed_slice(&self) -> Option<&'a [Bool]>

fn as_typed_slice_mut(&mut self) -> Option<&'a mut [Bool]>

impl Clone for Bool

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bool

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&Bool> for bool

fn from(v: &Bool) -> Self

Converts to this type from the input type.

impl From<Bool> for bool

fn from(v: Bool) -> Self

Converts to this type from the input type.

impl From<bool> for Bool

fn from(v: bool) -> Self

Converts to this type from the input type.

impl From<i32> for Bool

fn from(v: i32) -> Self

Converts to this type from the input type.

impl IsNA for Bool

fn is_na(&self) -> bool

impl PartialEq for Bool

fn eq(&self, other: &Bool) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Robj> for Bool

type Error = Error
