Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl SEXPTYPE

pub const OBJSXP: SEXPTYPE = SEXPTYPE::S4SXP

Alias for S4SXP (value 25).

R defines both OBJSXP and S4SXP as value 25. S4SXP is retained for backwards compatibility; OBJSXP is the preferred name.

pub fn type_name(self) -> &'static str

Get R’s name for this SEXPTYPE (e.g. "double", "integer", "list").

Returns the same string as R’s typeof() function.

Trait Implementations

impl Clone for SEXPTYPE

fn clone(&self) -> SEXPTYPE

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SEXPTYPE

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

Formats the value using the given formatter.

impl Hash for SEXPTYPE

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SEXPTYPE

fn eq(&self, other: &SEXPTYPE) -> 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.
