Enum VarKind 

pub enum VarKind {
    Scalar,
    Array,
    Hash,
}

Variable sigil classification for Perl’s three primary container types.

Perl distinguishes variables by their sigil prefix, which determines the container type and access semantics.

Variants

Scalar

Scalar variable ($foo) - holds a single value

Array

Array variable (@foo) - holds an ordered list

Hash

Hash variable (%foo) - holds key-value pairs

Implementations

impl VarKind

pub const fn sigil(self) -> &'static str

Returns the sigil character for this variable kind.

Examples

use perl_symbol_types::VarKind;

assert_eq!(VarKind::Scalar.sigil(), "$");
assert_eq!(VarKind::Array.sigil(), "@");
assert_eq!(VarKind::Hash.sigil(), "%");

Trait Implementations

impl Clone for VarKind

fn clone(&self) -> VarKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VarKind

fn deserialize<__D>( __deserializer: __D, ) -> Result<VarKind, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for VarKind

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

where __H: Hasher,

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 VarKind

fn eq(&self, other: &VarKind) -> 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 Serialize for VarKind

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
