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 Eq for SEXPTYPE

#[doc(hidden)]

fn assert_fields_are_eq(&self)

🔬This is a nightly-only experimental API. (derive_eq_internals)

#[doc(hidden)]

fn assert_receiver_is_total_eq(&self)

👎Deprecated since 1.95.0:

implementation detail of #[derive(Eq)]

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.

impl Copy for SEXPTYPE

impl StructuralPartialEq for SEXPTYPE

impl TrivialClone for SEXPTYPE

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
