Variants

Error

Error type (invalid type)

Warning

Warning type (e.g. unknown member on any)

Void

void – no value

Any

any – top type

Null

null

Bool

boolean

Int

integer

Real

real

String

string

Object

Object

Class(Option<String>)

Class or Class<ClassName> (the class/metatype value)

Instance(String)

Instance of a class (e.g. this inside a class; type of a variable declared as that class).

Array(Box<Type>)

Array or Array<T>

Map(Box<Type>, Box<Type>)

Map or Map<K, V>

Set(Box<Type>)

Set or Set<T>

Interval(Box<Type>)

Interval or Interval<T>

Function

Fields

args: Vec<Type>

return_type: Box<Type>

Compound(Vec<Type>)

Union: T1 | T2 | ...

Implementations

impl Type

pub const fn error() -> Type

Predefined type constants matching leekscript-java.

pub const fn warning() -> Type

pub const fn void() -> Type

pub const fn any() -> Type

pub const fn null() -> Type

pub const fn bool() -> Type

pub const fn int() -> Type

pub const fn real() -> Type

pub const fn string() -> Type

pub const fn object() -> Type

pub fn class(name: Option<String>) -> Type

pub fn instance(class_name: impl Into<String>) -> Type

pub fn array(element: Type) -> Type

pub fn map(key: Type, value: Type) -> Type

pub fn set(element: Type) -> Type

pub fn interval(element: Type) -> Type

pub fn function(args: Vec<Type>, return_type: Type) -> Type

pub fn compound(types: Vec<Type>) -> Type

pub fn compound2(a: Type, b: Type) -> Type

Build compound from two types (e.g. T1 | T2).

pub fn non_null(ty: &Type) -> Type

Type with null removed from a union. For A | null returns A; for A returns A.

impl Type

pub fn code(&self) -> String

Name/code as in source (getCode() in Java). Uses Display for full representation.

pub fn for_annotation(&self) -> String

Format for type annotations (e.g. hover, completion). Uses type? instead of type | null at every level, so e.g. Array<Cell | null> shows as Array<Cell?>.

pub fn is_primitive_number(&self) -> bool

pub fn is_number(&self) -> bool

pub fn is_array(&self) -> bool

pub fn is_map(&self) -> bool

pub fn can_be_null(&self) -> bool

pub fn is_primitive(&self) -> bool

impl Type

pub fn assignable_from(&self, other: &Type) -> bool

Whether a value of type other can be assigned to a variable of type self (self = target, other = source).

pub fn check_cast(from: &Type, to: &Type) -> CastType

Classify the cast from expression type from to target type to.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Display for Type

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

Formats the value using the given formatter.

impl Hash for Type

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 Type

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