object: every type converts to it.

§

Dynamic

dynamic: checked when the code runs, not here.

§

Void

§

Null

null before it meets a type.

§

Text

Translatable text: t"key".

§

Unit(String)

A quantity with a unit: Ticks, Seconds, Blocks, a mod’s own.

§

Content(String)

A content reference of a kind: @item:… is Content("item").

§

Tag

§

Own(String, Vec<Type>)

A type the source declares, by name, with its type arguments (Box<i32>; none when it isn’t generic).

§

Param(String)

A type parameter (T) where its argument isn’t known: in its generic’s own code, or a method’s before inference.

§

Static(String)

An own type named where a value goes (Mode in Mode.Idle): its static members and its cases.

§

Game(String)

A game class, by its internal name (.yns only).

§

Yog(String)

Yog’s: a handle (Player), a domain’s group (Chat), a struct or an enum an action answers with — by name.

§

Namespace(String)

A namespace (Game.World), on the way to what’s in it.

§

List(Box<Type>)

§

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

§

Tuple(Vec<Type>)

§

Fn(Vec<Type>, Box<Type>)

A delegate: Action<A, B> (its result void), Func<A, R>.

§

Nullable(Box<Type>)

§

Unknown

Not known here (the library’s, or what couldn’t be typed): checks involving it pass, so one gap doesn’t cascade.

Implementations§

Source§

impl Type

Source

pub fn own(name: impl Into<String>) -> Type

An own type that isn’t generic.

Source

pub fn nullable(self) -> Type

Source

pub fn non_null(&self) -> &Type

The type without its ?.

Source

pub fn is_nullable(&self) -> bool

Source

pub fn known(&self) -> bool

Source

pub fn is_numeric(&self) -> bool

Source

pub fn converts_to(&self, to: &Type) -> bool

Whether a value of self goes where to is wanted without a cast.

Source

pub fn wider(a: &Type, b: &Type) -> Type

The type both of two numbers become in an operation (i32 + f64 is f64).
