Enum OneOrCollection 

pub enum OneOrCollection<T> {
    One(T),
    Collection(T),
}

One item or collection of items for types.

This is common construction in compiler when we need to describe singleton or collection of items of specific type.

Variants

One(T)

Collection(T)

Implementations

impl OneOrCollection<TaggedType<QualifiedName, QualifiedTypeNameTag>>

pub const fn qualified_type_name(&self) -> &QualifiedTypeName

impl<T> OneOrCollection<T>

pub const fn inner(&self) -> &T

Inner type.

impl<T> OneOrCollection<T>

pub fn map<F, R>(self, f: F) -> OneOrCollection<R>

where F: FnOnce(T) -> R,

Trait Implementations

impl<T: Clone> Clone for OneOrCollection<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for OneOrCollection<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for OneOrCollection<T>

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.
