Variants

Empty

Literal(TyLit)

Named(String)

Parameterized(Box<Ty>, Box<Ty>)

AnyOf(Vec<Ty>)

Function(TyFunc)

Table(Frame)

Infer

Means that we have no information about the type of the variable and that it should be inferred from other usages.

Trait Implementations

impl Clone for Ty

fn clone(&self) -> Ty

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ty

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

Formats the value using the given formatter.

impl Default for Ty

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Ty

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

Deserialize this value from the given Serde deserializer.

impl Display for Ty

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

Formats the value using the given formatter.

impl From<TyLit> for Ty

fn from(lit: TyLit) -> Self

Converts to this type from the input type.

impl PartialEq<Ty> for Ty

fn eq(&self, other: &Ty) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Ty> for Ty

Implements a partial ordering or types:

• higher up are types that include many others (AnyOf, Any) and
• on the bottom are the atomic types (bool, string).

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Ty

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

Serialize this value into the given Serde serializer.
