Struct EnumType

pub struct EnumType { /* private fields */ }

A type that has multiple possible states.

Implementations

impl EnumType

pub fn new<S: Into<Arc<str>>>( name: Option<TypeIdentifier>, cases: impl IntoIterator<Item = S>, ) -> Result<Self>

Creates a new enumeration from the list of case names. The case names must be unique.

pub fn name(&self) -> Option<&TypeIdentifier>

Gets the name of this type, if any.

pub fn cases(&self) -> impl ExactSizeIterator<Item = &str>

Gets a list of all cases in this enum.

Trait Implementations

impl Clone for EnumType

fn clone(&self) -> EnumType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnumType

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

Formats the value using the given formatter.

impl Hash for EnumType

fn hash<H: Hasher>(&self, state: &mut H)

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 EnumType

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