PHP built-in type keyword — zero-cost alternative to Name::Simple for the 20 reserved type names. One byte instead of a Cow<str> + Span in the AST.

Variants

Int = 0

int — integer scalar type.

Integer = 1

integer — alias for int, accepted in type casts.

Float = 2

float — floating-point scalar type.

Double = 3

double — alias for float, accepted in type casts.

String = 4

string — string scalar type.

Bool = 5

bool — boolean scalar type.

Boolean = 6

boolean — alias for bool, accepted in type casts.

Void = 7

void — return-only type indicating no value is returned.

Never = 8

never — return-only type for functions that never return normally (PHP 8.1+).

Mixed = 9

mixed — top type; accepts any value.

Object = 10

object — any object instance.

Iterable = 11

iterable — array or Traversable (deprecated in PHP 8.2; use array|Traversable).

Callable = 12

callable — any callable value.

Array = 13

array — any PHP array.

Self_ = 14

self — refers to the class in which the type hint appears.

Parent_ = 15

parent — refers to the parent class of the class in which the type hint appears.

Static = 16

static — late-static-bound type; the class on which the method was called.

Null = 17

null — the null type; only valid in union types.

True = 18

true — the literal boolean true (PHP 8.2+).

False = 19

false — the literal boolean false.

Implementations

impl BuiltinType

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

Returns the canonical lowercase spelling used in PHP and in serialized output.

Trait Implementations

impl Clone for BuiltinType

fn clone(&self) -> BuiltinType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuiltinType

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

Formats the value using the given formatter.

impl PartialEq for BuiltinType

fn eq(&self, other: &BuiltinType) -> 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 BuiltinType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
