Enum Type

pub enum Type {
    Any,
    Null,
    Bool,
    Integer,
    Float,
    Text,
    List(Box<Type>),
    Dictionary(Box<Type>),

    Or(Vec<Type>),
    Opaque(String),
}

The type of a Ryan value.

Variants

Any

Any type. Matches anything.

Null

The null type. Matches only null.

Bool

A boolean.

Integer

An integer.

Float

A float.

Text

Some text.

List(Box<Type>)

A list where all elements are of the same type.

Dictionary(Box<Type>)

A dictionary where all the values are of the same type.

Tuple(Vec<Type>)

A list of given length where each element has a specific type.

Record(IndexMap<String, Type>)

A map where the given keys correspond to values of the given types.

StrictRecord(IndexMap<String, Type>)

A map containing only the given keys corresponding to values of the given types.

Or(Vec<Type>)

A value that can be of any of the values in a list.

Opaque(String)

A type which cannot be inspected. This variant cannot be created directly from Ryan code.

Implementations

impl Type

pub fn matches(&self, value: &Value) -> bool

Checks whether a given value corresponds to the given type.

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

Formats the value using the given formatter.

impl Display for Type

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

Formats the value using the given formatter.

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.
